On my main Intel MBP I've had this same issue since Catalina. I just got a new M1 MBP, without all the Intel baggage, and still I have the issue.
On Big Sur 11.2 (just released as of Feb 1 2021), on my M1 Mac, I get a KP on reboot nearly every time...
Does anyone know what I can do to resolve this? I have constant KP on reboot!

OK I've FINALLY been able to reliably reproduce this issue!!
Install Ruby with Home-brew.
Run "gem update".
Reboot and you'll see the panic.
I don't think it's a ruby issue, but something that running the non-system ruby causes issues...
So weird.
I've rebooted say 25 times, and only on the 3 I ran gem, did I see the issue.
Update2:
I can consistently reproduce it using a number of ways, and it's weird. All of these apps are installed via home-brew -
Using ruby and then gem installed via home-brew, i.e. executing /opt/homebrew/opt/ruby/bin/ruby, then /opt/homebrew/opt/ruby/bin/gem, then rebooting - see KP.
Executing "thef*ck" (https://github.com/nvbn/thef*ck) - see KP.
Executing "pip3 list" installed via homebrew, i.e. "/opt/homebrew/bin/pip3 list" - see KP.
Update3 SOLVED:
My replication steps only work when my terminal emulator (iTerm/Terminal) was in added in "Developer Tools" section of Security & Privacy settings in macOS.
Removed them and I could not longer replicate.
This looks to be a bug in codesign/watchdogd/adhoc signatures. Where you remove the terminal from dev tools, you can see the signature check is performed and all is well.
If you have terminal in the "developer tools" category, certain tools (like the ones I describe in my post, ruby/pip), cause the OS to panic on reboot, as something ends up hanging.
