There has been at least one user that reported a KP after a clean install with nothing but the base OS loaded and no peripherals attached.
That kinda shoots down the "strictly app/connected peripheral related" theory.
Got a tip for us?

I wonder if they chose APFS or Mac OS extended as a SSDs format. Default is APFS for t1/t2 enable Macs on SSDs but can be changed when re-formatting.
Yup, that was me. Wasn’t a damned thing installed or connected. So “Chris” can kiss my *** hahaha
Level 3 support anyone?
There are others who have reported the same, both here and on other forums as well as in response to that video what was posted earlier.
Everything default. Just a routine setup. Did the initial setup, took a break to let my dogs out. Pressed a button to wake the computer when I came back in. Nope. Had to hold down the power button and it started up the the Your computer was shut down BridgeOS KP

Perhaps the firmware didn't properly install/complete. I wonder if Apple is considering a way to re-flash the firmware from the July supplemental update and if there is anyway to test if the firmware has not properly installed.

Firmware wasn’t even installed at that point. I literally only did the initial setup. When I called them they wanted that one back and worked out an advanced replacement for it.
Unfortunately the second came with with physical damage and was never even setup.
So currently working with unit 3. Mostly been OK. No crashes, but it did freeze once and wouldn’t boot without a SMC reset and I get some random run away heat issues. Even with simple things like attaching my phone to sync. But then I can’t get it to replicate after. It’s infrequent, but it’s annoying and in that case it’s one of their own apps.
Edit: This afternoon I installed the latest Mojave beta. I can’t leave it installed because I have software that won’t run on it, but hoping the firmware update that stays behind even after a roll back solves the random temp issues. But I have a long weekend, so will leave it installed until Monday.
That might stand to reason with the freeze I had that required an SMC reset, before it would boot?
When you did your SMC reset, which steps did you use? The steps on their site have 2 parts, holding the power button, and then ctrl+opt+shift+power. I've never had a successful boot after doing the second combo. It also seems like a different key combo than NVRAM but it doesn't specify what it does.
Edit: second time in this thread I've said a swear instead of shift lol
Only the first steps, because that did resolve the issue. The additional steps I believe are to be used if the first steps don’t resolve it?
I think you forgot to click your heels together 3 times.
Code:
Mac notebook computers with the Apple T2 chip
Try this first:
1. Choose Apple menu > Shut Down.
2. After your Mac shuts down, press and hold its power button for 10 seconds.
3. Release the power button, then wait a few seconds.
4. Press the power button again to turn on your Mac.
If that doesn't resolve the issue, follow these steps:
1. Choose Apple menu > Shut Down.
2. After your Mac shuts down, press and hold for 7 seconds:
a. Right Shift key,
b. Left Option key,
c. Left Control key
d. Then keep holding those keys while you press and hold the power button for another 7 seconds.
3. Release all three keys and the power button, then wait a few seconds.
4. Press the power button again to turn on your Mac.Yeah, consider my issue "unresolved"
Thanks for conveniently quoting this lol. Part of my issue is when do I do the second steps? I think the last time, I did JUST the first steps, then at the login screen, shut down and did JUST the second steps. I get the apple logo and a loading bar that stops at ~60% and never gets further. I tried leaving it overnight last time :/
I'm still experiencing the KP on wake issue after installing the supplemental update. I'm working with apple and providing diagnostic dumps after it occurs.
I hope that they have extended your return period while you help them beta test?
Maybe I am wrong about this, but I think if it was an issue with a firmware not being properly installed that I would have one of those boot loop issues and would have to do a firmware reset as outlined here?

Nothing. No peripherals attached. No apps installed. Can't get any cleaner than that. I guess it's possible some peripherals are causing KPs, but there is a more fundamental problem here that Apple needs to get to the bottom of. They won't find it if they continue associating it with peripherals.
Maybe this thread can be more useful if people with (and without) problems can post their configurations. I wonder if there's a pattern.
i9/32gb/2.9Ghz/1tb/560X/Silver, yes post the color, maybe that makes a difference

i9/32gb/2.9Ghz/2tb/560x/Space Gray. No issues.

i9/32/2.9/512/560X/SG. No kp's (since eliminating TS3+) with 1, 2, or 0 LG 4k's using dp->usbc cable.
18 days and counting kp free, both before and after supp2.
(Previously had kp on wake every morning when monitors were connected via TS3+. I did NVRAM and SMC reset while I was using the TS3+ which didn't help. Did both resets again after eliminating the TS3+.)
Base model 15 i7/16/2.2/250/555X/Silver
i7/16/2.2/250/555X/SilverCan you describe which steps you did of the SMC reset?
i9/32gb/2.9Ghz/1tb/560X/Silver, yes post the color, maybe that makes a difference
Currently same configuration as yours, except Space Gray.
However the unit that I had that KP’ed after initial setup was i9/16gb/1tb/560x SG.
space grey = no kp confirmedddddd!!!!!
Base model 15
Can you describe which steps you did of the SMC reset?
Followed steps at https://support.apple.com/en-us/HT201295
Shutdown, hold power button for 10 sec, release for "few" secs, power button to startup.
Have you ever attempted the second part? Sorry for harping on this but I've never had a successful boot after trying that second part so I'm curious to see if anyone else can.
Nope, never tried. Didn’t even read that far until now... had to go see what you meant by second part...
