Suspecting corrupted VBIOS after update of AMDGPU on AMD7870

[Liu, Zhan]

Okay I see. From your attached dmesg.log, issue comes from here:

[   26.265638] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, signaled seq=1, emitted seq=2
[   26.265764] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process  pid 0 thread  pid 0
[   26.265771] [drm] GPU recovery disabled.

There was a very similar issue that’s recently fixed and merged in 5.5 kernel. I’ve noticed that you are using 5.4 kernel, so you can give 5.5 a spin to see what happens.

As for these “Green Dots” at BIOS initialization stage, the main amdgpu driver was not loaded yet, so it shouldn’t related to amdgpu.

BTW, your new findings (https://gist.github.com/Kreyren/3e55e9a754e58956e1690e38b1888de7) gives me 404. Please fix the link. Good luck!

Warm regards,
Zhan

Hello Zhan,
Here is it:
https://gist.githubusercontent.com/Kreyren/e35587d8710e63e511e69d8653fd996b/raw/628df1c76ff99adab1d2161e6a20f631de101d5c/gistfile1.txt<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgist.githubusercontent.com%2FKreyren%2Fe35587d8710e63e511e69d8653fd996b%2Fraw%2F628df1c76ff99adab1d2161e6a20f631de101d5c%2Fgistfile1.txt&data=02%7C01%7CZhan.Liu%40amd.com%7C2fe63c116bbd4cacddc008d7a5d79126%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637160218197534666&sdata=CGBp3z6G8KJXT9cyfaJxlDlkpaDF36qTsj228KYo1bk%3D&reserved=0>

Note that I'm updating previous gists with new findings (https://gist.github.com/Kreyren/3e55e9a754e58956e1690e38b1888de7).<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgist.github.com%2FKreyren%2F3e55e9a754e58956e1690e38b1888de7).&data=02%7C01%7CZhan.Liu%40amd.com%7C2fe63c116bbd4cacddc008d7a5d79126%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637160218197544657&sdata=C8pB8txk8a9du6ulzG%2FA15VBF8vTXfjZ%2BG9vU9%2FFkCw%3D&reserved=0>

If relevant i'm also getting these 'Green dots' at the initialization of bios (https://linx.li/s/8j3poh2z.png<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Flinx.li%2Fs%2F8j3poh2z.png&data=02%7C01%7CZhan.Liu%40amd.com%7C2fe63c116bbd4cacddc008d7a5d79126%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637160218197544657&sdata=ZuobmBcSLCHK97ta%2FLG5txQCf0vN%2BS47UGRNAlPZu2s%3D&reserved=0>).
These dots are not present anywhere else and were not present before said update.

Thanks,

Hi Jacob,

Thant you for your bug reporting.

I saw you attached xorg.log, which is great. Could you also grab dmesg.log via SSH?

Thanks,
Zhan

Hello,
I believe that system update that included amdgpu on debian testing (but i am on LFS) corrupted my VBIOS on AMD7870 (+- 4 hours after the update the GPU using AMDGPU/Radeon drivers resulted in no output).
i'm sending this email to inform about possible bug with my findings on https://gist.github.com/Kreyren/3e55e9a754e58956e1690e38b1888de7<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgist.github.com%2FKreyren%2F3e55e9a754e58956e1690e38b1888de7&data=02%7C01%7CZhan.Liu%40amd.com%7C2fe63c116bbd4cacddc008d7a5d79126%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637160218197554652&sdata=goaR7sDaBxHkmG%2Biln%2FsxEZfSqQ7KTqwbxc9FRxGGMs%3D&reserved=0> and i would appreciate any help in excluding VBIOS corruption from the diagnostics.
Thanks,
