Regression found on x86-64 AMD (ASUS GA503QR, Cezanne platform) 
somewhere between 7f9a9d5d9983 and 5.15.3-rc1. The very early -rc1 tag 
from a day and a half ago boots fine, -rc1 final and -rc2 boot into a 
kernel panic during init.

Unfortunately I can't gather any useful debug info from the panic as the 
relevant bits are instantly pushed off the screen by rest of the dump.
	
Here's what I'm left with on screen after the panic, hopefully someone 
can get something useful out of it:

I'll bisect and try to narrow this down some today but I'm running 
builds on my laptop while I work so it won't be super quick.
