2018 MacBook Pros crashing with "Bridge OS" error

Search back through the thread and look for the word capture. Then call Apple and lovingly explain the issue you’re having and find out if they’d like to capture a brand new unit having a replicable issue. They probably will.
I have already opened a case and ran capture and sent over the log. They haven't gotten back to me and certainly hasn't offered to replace my machine. You mean I am entitled to an exchange?
Still having daily crashes, although I'm on the latest beta of Mojave.
[doublepost=1535980397][/doublepost]Can I ask for those who aren't crashing - what is your Thunderbolt controller firmware version number? (Apple > About > System Report > Thunderbolt.)
Are we all on 30.2 or are some of us on 33.2?
CalDigit advised the latest version should be 33.2, just trying to cover all bases.

It being new barring special circumstances (bought through Apple’s employee purchase program) you can return it within 14 days for any reason. And alternately they have been asking for many of these as samples for their engineering team in which case you’d get a replacement.
30.2 here
HS 10.13.6 SU 2.
Have never installed Mojave
No KP's
Edit: Although I tested connecting to an external display via TB -to- HDMI dongle once, my machine does not normally spend time connected to anything external. I have plugged in an external USB drive to do TM Backups twice in the last month. Also, I have no Bluetooth devices, so I just leave Bluetooth turned off.

Latest Mojave beta and I'm on 30.2.
I haven't had a crash in at least 3 weeks, maybe a month. I'd have to look back at my posts to see when it actually happened. It has been that long. Everything is rock solid currently.
I wonder where they're getting this 33.2. Of course vendors may have info we dont. I sent in my dock a bit ago back to Henge for a firmware update which stopped my drives from disconnecting, apparently that was an issue Apple was aware of and working with them on, and seems to have been fixed. So someone is working with someone else on something, I guess 
I'd actually say I've gotten more crashes after this update, I haven't gone 24 hours without one yet.

Its interesting there was an article a while back about Apple software updates failing to update firmware along with OS versions..I wonder where they're getting this 33.2.

Heres a tool to check EFI versions - EFIgy-1.0.1.zip 2.05 MB
I would return it / exchange it. I've only had 3 KPs total since I brought mine on the 14th, and none in the past 10 days.
Mine has never had a crash. Purchased 7/15
Firmware version 30.2
Nothing ever attached except power cord
Supplemental update #2 hasn't been installed
That seems to be applying to imac, though it's curious that macbooks are currently shipping with a lower version.
I have a few different 3rd party USB-C SSD caddies. I've been leaving them attached during sleep trying to get a KP and no KP in the past 10 days so far.
I have only: (a) Logitech USB external keyboard, (b) HDMI to 1080P BenQ Monitor, (c) Apple power connector, all connected to a single Apple Digital AV adapter

Nope. Myself: 3 KPs, no Thunderbolt devices.
There have also been at least two different people that had KPs after erasing / formatting the SSD, reinstalling HS, and no additional software, nothing connected. Totally bare clean OS & completely stock hardware with KPs.

Looks like the venerable "Bad Magic" kernel panic.
I've had a 2018 15" MBP just about since release. Experienced the KP issue semi-regularly when waking from sleep while connected to the LG UltraFine 4K Display via Thunderbolt 3. Also heard the fan come on even when performing light tasks, which never happened with my 2016 13" MBP.
No issues since the supplemental update. All is running as it should!
With that resolved, and with the tweaks to the keyboard, I am loving this machine. Yes, it gets a bit warm when charging from the 61W power supply built into the monitor, but that's expected since the 15" is looking for 87W. When I plug in the charge cable as well as the monitor, all is cool as a cucumber.

Apple has identified a manufacturing defect in some iPhone 8s that is causing some of them to malfunction.
I wonder if we may get an admission of a similar sort about some of the 2018 MacBook Pro's that folks are having trouble with?
