Hi Acelan,
The first bad commit:
commit 224dffc89a957e2f006de3202d12c09bf348f992 (refs/bisect/bad)

drm/amdgpu: make sure to init common IP before gmc
BugLink: https://launchpad.net/bugs/2000110
Move common IP init before GMC init so that HDP gets
remapped before GMC init which uses it.
This fixes the Unsupported Request error reported through
AER during driver load. The error happens as a write happens
to the remap offset before real remapping is done.
Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373
The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.
Fixes: 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in
get_port_device_capability()")

ThinkPad L14 Gen 3 blank laptop screen on bootup

Bug description:
When booting linux-image-5.17.0-1026-oem version 5.17.0.1026.27 on a
Lenovo ThinkPad L14 Gen 3 AMD (model 21C5CTO1WW), the screen goes
blank shortly after bootup.
As far as I can tell (the screen blanks pretty quickly, so I'm not
100% sure), the last message before the screen disappears is this one:
Jan 9 07:58:30 work kernel: [ 1.321487] fb0: switching to amdgpu
from EFI VGA
Booting linux-image-5.17.0-1025-oem version 5.17.0.1025.26 works fine,
so this appears to be a regression in whatever changes there were in
the framebuffer/amdgpu drivers between 5.17.0.1025.26 and
5.17.0.1026.27.
I think this should be high priority, because it gives the impression
that the system is completely borked, when in actuality it's probably
just waiting for me to enter my drive encryption password.
If I type the encryption password, it seems to progress to starting
the system (the microphone mute LED comes on as expected), but even X
starting does not turn the screen back on. Switching to the frame
buffer console with Ctrl-Alt-Fx does nothing.
