Public bug reported:
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.
