This may sound stupid, but for the reboot issue (KP on reboot - watchdogd etc), I simply start the machine then open terminal.
I then execute a couple of commands, such as gem or top, then reboot.
Got a tip for us?

I can not directly recreate it. But it happens pretty frequently when screen sharing. If I do anything heavy while screen sharing it crashes. I am currently (7 months later) still running on one monitor. I have a 2019 MacBook Pro 15 that has had it's logic board replaced. This is def NOT a hardware problem.
EDIT: I only get the watchdog error on my end. Fans run at full, waits about 2 minutes, can't control the screen then it reboots.
Yes, I agree with you this is def not a hardware issue. Cause all new and old mac has got this issue which @johnalan has both type macs.
If we can recreate the crash then we can make a video and send to apple as feedback. Cause Apple is more responsive to video feedback, I sent many video bugs for Big Sur and they always sent me a response when they fix the problem.
Have you looked at the logs to see what's going on during shutdown. I haven't timed it but I feel like the shutdown in that YT video is taking longer than usual - perhaps something is blocking a proper shutdown?
I had the same problem for months with several panics a day. Disabling SIP fixed it and I have been running for weeks with no crashes.
@Brian33 Suggested I check this out and I ended up turning off the display never in energy saver and so far no watchdog KP. Before this I couldn't even watch more than one video on youtube without a KP. so far I'm 4 videos in. Will update.
I formatted and clean installed, but am still getting KP watchdog. Also interested in running without the SIP because I'm a bit of a newb and don't want to add to the challenge. on a late 2015 iMac running OS 11.1 i5 intel. This is my first time on a mac in 10 years! What a re-intro! Hahah!
Nope. KP Watchdog after 5 youtube vids. At least I got to watch some comedy!
There are two types of KP being discussed here.
KP during shutdown/reboot only. Otherwise comp works fine. Here disabling SIP helps. (atleast works for me)
KP during use. related to WindowServer. This seems to have lot more causes.
Here I pasted above two types of crash logs.
Constant Kernel Panics – userspace watchdog timeout: no successful checkins from com.apple.WindowServer
It is not clear how widespread this issue is. It would be useful to have poll to find out. I have seen people reporting two types of panics. I get Type 1 and only on reboot/shutdown. Otherwise, I have no problems. Type 2 seems more problematic, but I have not seen it. Type 1 panic(cpu 2...

That means you can recreate the KP by watching a video. That is great news. 🥳 Please make a video (this can be a long video after watching 5 vids 😀 but you can easily cut it, for making the video use Screenshot App under the Applications/Utilities Folder) and send it to Apple as Feedback. But don't use online feedback use Feedback Assistant from the System. To do that; open the Spotlight and make a search, cause if you not using any Beta version of OS this app is hidden.
Coming into this thread 39 pages in...
I am a 16" MBP owner and it seems since upgrading to Big Sur a few months ago I have been getting constant Kernel panics.
I did try the trick of disabling settings under BATTERY (Power nap and graphics switching) but that did nothing.
Been on the phone with Apple Tier 2 support. We did a diagnostic test and the results came up with no issues. So, this pretty much rules out a Logic Board failure.
I think I may have discovered the issue for my cause and it has been reported in this very thread as a Google search brought me here in the first place...
Caldigit. I own two of their docks.
There have been many reports that Caldigit docks are responsible for these kernel panics.
I went into my Macintosh HD -> Library -> Extensions and removed the Caldigit extension.
Thus far, no kernel panics. However, I am not certain if this completely fixed the problem or not. I am only on my first full day of no panics.
Has anyone else found a viable solution to these panics? I'd rather not read 39 pages of information.
Thanks everyone!

Short Answer: No.
Long Answer: Also, no.
- Some users have found workarounds. IE: I never let my 16" MPB sleep, turn off hard disks or anything relating to power saving. Its all on, all the time and I restart it when it misbehaves (which is a few times a week) but like I said, workaround...
- Some users experience these KP's on vanilla machines with zero third part software installed or third party hardware attached. "Out-of-the-box" if you will...
Apple asked me to remove Kernel Extension they believed were causing my KP's. Two things to note in MY specific scenario:
Removing the extensions rendered this machine useless to me, essentially a $3800 machine that can surf the web and inconsistently do email (mac mail still randomly fails). the software in question for me is UAudio which builds Music Production Software and Hardware specifically for mac. Without it, I have no use for this computer.
The apple tech I was corresponding with at the time ensured me that removing these extensions would NOT interfere with my use of UAudio Software and Hardware. He was wrong. I appeased apple and removed the extensions in effort to resolve the problem. The KP's were not as frequent but did still exist. Later that day I re-installed the software (for obvious reasons) and as long as I follow my workaround I don't have any KP's. Apple gave up on my ticket and I haven't had any correspondence as they are instant on those extensions being the issue even though I have reported differently.
None of my software is compatible with Big Sur yet, all I can speak to is Catalina.
2018 Mac Mini with eGPU (RX 580) running 10.15.7 and KP every time after resuming from sleep and playing a few seconds of any YouTube video in Safari. If I close and reopen Safari after resuming from sleep, no KP.
If I disconnect the eGPU and use the integrated Intel 630 graphics, no KP with Safari and YouTube videos.
This seemed to start around 10.15.5 for me.
Although it's a nuisance, I'm now in the habit of closing and reopening Safari after each resume from sleep in order to avoid KPs.

Interesting combination.
Do you have any extensions installed in Safari? (Safari Preferences -> Extensions)
Update: Removing the CalDigit extension made no difference though after removal kernel panics began happening every two days instead of every few hours.
I am back to constant kernel panics on this damn 16" MBP and no particular help from Apple support to resolve it.

An update from my side - knocking on wood while typing... 
:
I've upgraded to Big Sur 11.0.1 a few weeks ago and haven't had a KP ever since; HOWEVER - please keep reading! - it might have to do with a small change during the upgrade: I've disconnected my CalDigit TB3 Pro-Dock with my two 27" 4K Eizos for the update and hooked the MBP to the OEM Power Supply (87W). The upgrade went through fine and after reconnecting the ProDock I simply kept the OEM Power Supply plugged in.
Perhaps THIS is why I haven't seen any KPs lately?
All the remediation attempts, e.g. turning off automatic standby or display sleep, point into the direction that there might be some issues with the power management.
When waking the displays, at least one sometimes experienced a series of "hiccups" until it was stable (switching resolutions/flickering screen etc.). As the only connection to the MBP transmits not only the TB3/DP-signals but acts as the power source as well, my guess is that it MIGHT be unstable at times, triggering some odd effects due to power fluctiations (yes, the MBP has an internal battery which should kinda act as an UPS, but maybe the power controller is unable to account for the "flickering" introduced and some brief intervals of undervoltage result in CPU crashes and ultimately a KP)...
I'm aware that there are guys out there with desktop Macs who are also experiencing KPs - but from what I've read here it is likely that there is more than one reason for these KPs to appear, so to you guys with MacBooks out there: give it a try and hook up your OEM Power Adapter (as far as it is more powerful as the TB3 dock's power supply to the device, otherwise MacOS or the SMC will simply use the more powerful one) in parallel to your TB3 dock connection and see what happens.
Looking forward to your reports!

I am trying to make sense of what you are recommending.
It sounds like we should plug the OEM charger into the CalDigit dock?
I don't know if that will work. I'll tell you why. I have BOTH the OEM charger and a TB3 cable to the powered dock. Why both inputs? The CalDigit dock cannot sustain the 16" MBP charge (even with the firmware update) so I have my OEM charger plugged in as well to keep the 16" at 100% charge.
So, with the laptop already selecting the OEM charger as the more powerful power source I am still getting kernel panics.
I don't mind trying your solution, though.
What is pissing me off is CalDigit. I had a very good relationship with their support team. They would always immediately answer my inquiries. When I sent them an email asking about this issue and their drivers they went completely silent. I got a read receipt that they opened my email but they never responded. It seems to me they don't want to give any more statements about this issue since there is a high probability their dock is causing it.
Hi NJRonbo,
no no, there is no use in plugging the OEM power supply into the dock - what I meant is hooking it up to the MacBook.
If you've already done that and are still experiencing KPs, that's rather discouraging.
As to the issues maybe being caused by the CalDigit-Docks: maybe we should do a poll as to which make and model of dock the guys in here are using that are getting KPs? Maybe it only points to CalDigit as their docks are very popular, but the KPs also happen with other types of docks?
I have the Caldigit TS3 and Caldigit TS3+ as I use the laptop in two different locations.
I did remove their extension out of my HD -> Library -> Extensions
That did nothing. I just got a kernel panic seconds ago (which made me come here) and I have both the dock and the OEM charger plugged into my laptop.
At this point, since I have been talking with Apple Tier-2 support, whether its worth getting this laptop repaired or if its a software or peripheral issue. Since the latter is extremely difficult to pinpoint I am kind of going with telling Apple that I want this repaired or replaced.

Hi, could you tell me if the glitches look like this ?
Thanks
Imac 27 "2020 glitches - AMD Radeon Pro 5700 XT 16 Go
Hi everyone, I'm experiencing this since a few weeks with my 2020 iMac 27 - AMD Radeon Pro 5700 XT 16 Go. Sound remains ok when glitches come, but the iMac completely freezes and I must restart (hard reboot) NVRAM, PRAM, SMC done but nothing changes. Any help would be appreciated, thanks.

I think it could be hardware related. I have the RX 5700 XT in my old Mac Pro from 2010 (which isn't even officially supported to run Big Sur) and I don't have any problems anymore since Big Sur and I game from time to time.
The behavior you describe sounds like how things behaved in Windows 10 for me until I decied to return the RX 5700 XT I initially had – the reseller could reproduce the problem and gave ma a replacement card which has been stable.
I used to get a watchdog KP every now and then when waking from sleep in Catalina (display stayed black and eventually the computer restarted) but it hasn't happened since Big Sur for me.
Yes, Ad Block Plus. However, I found that disabling hibernation mode on my Mac Mini fixed the problem. No kernel panics when resuming from sleep since making the following changes which were referenced in another thread (below).
sudo pmset hibernatemode 0
sudo pmset autopoweroff 0
sudo pmset standby 0
MacOS Catalina 10.15.3 - crash panic(cpu 0 caller 0xffffff801faa2d1c): Sleep transition timed out after 180 seconds while calling power state change
The problem persists and has been there for a long time now. The only visibile solution has been to replace logic boards. And some of the time this does not address it either (probably because those are refurbished). Given its age I would lodge a request with Apple to adrdress your individual...

Actually, the problem occurs randomly but only when Mainstage is opened, that's the reason why I would go with a software issue, what do you think ?
Thanks
