Description:

After upgrading from 5.14.11-arch1-1 to 5.15.6.arch2-1 , I get a kernel oops on every boot.
Trying to shut down the machine will result in a system hang and it is impossible to unmount or reboot the machines using sysrq.
Syncing the disk using sysrq is still working, but one is forced to hard turn off the machine, resulting in a dirty journal.


Additional info:

Machine is a CTL Chromebox running Mr.Chromebox's coreboot 4.14 build and booting using EDK2/Tianocore UEFI.
Full dmesg of 5.14 and 5.15 is shareable on request.


Steps to reproduce:

simply boot the system and get the following in dmseg:

Comment by Jann Foehringer (JannF) - Wednesday, 08 December 2021, 21:06 GMT
dug as far as I could and this seems to have been introduced by this commit: https://github.com/torvalds/linux/commit/a8db7a3f8ac69e558c7bfbd04802201c39a104ad

So it may or may not be an arch issue and I filed a bug report here: https://bugzilla.kernel.org/show_bug.cgi?id=215269
