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'm going to mark this as high, 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.
