I'd like some help troubleshooting why I can't boot with 5.10.27, when 5.4.97 boots fine.
My GPU is an AMD RX 270.
When trying to boot the 5.10 or 5.12, output is normal up until the point where KMS happens, but it never switches to a higher resolution and just shows the last pre-KMS frame.
The system carries on responding to keyboard events, and can be shut down gracefully with the power button, so I don't think this is a crash.
I think it's unlikely that both 5.10.27 and 5.12.2 have a bug with my GPU, which leads me to believe it's an issue with my config.
EDIT:
I retrieved the dmesg by changing /etc/conf.d/dmesg.
It contained an error that flashing amdgpu/pitcairn_uvd.bin failed, which makes sense because it wasn't in my list of firmware files.
I changed my list of firmware files to: | Code: | amdgpu/pitcairn_ce.bin
amdgpu/pitcairn_mc.bin
amdgpu/pitcairn_me.bin
amdgpu/pitcairn_pfp.bin
amdgpu/pitcairn_rlc.bin
amdgpu/pitcairn_smc.bin
amdgpu/pitcairn_k_smc.bin
amdgpu/pitcairn_uvd.bin
radeon/TAHITI_vce.bin |
... and after rebuilding the kernel everything worked fine. I think the wiki list should be updated, as it proposes loading everything from radeon/ , but I distinctly remember switching to amdgpu/ for a reason. Also, pitcairn_uvd isn't available in radeon/ at all. |
