Title:
amdgpu hangs for 90 seconds at a time in 5.13.0-23, but 5.13.0-22
works
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Impish:
Confirmed
Bug description:
SRU Justification
Impact:
This does not occur with linux-image-5.13.0-22-generic, but does with
linux-image-5.13.0-23-generic.
On startup, I get about a 60 second hang, with the following in the kernel
dmesg:
Jan 4 15:26:36 inspiron-3505 kernel: [ 34.160572] amdgpu 0000:04:00.0:
amdgp : failed to write reg 28b4 wait reg 28c6

I have the following GPU:
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Picass
o (rev c2) (prog-if 00 [VGA controller])
04:00.0 0300: 1002:15d8 (rev c2)
(This is a Ryzen 5 3450U CPU with Radeon Vega Mobile.)
I get a similar hang if I start firefox (when it's probing OpenGL
contexts), and even with glxgears and glxinfo. Seems like anything
that'd kick on a OpenGL context does it. I had a freeze as well when
I tried running firefox and glxgears both. Along with odd BUG:
messages logged (I have some in the attached log.)
I was running with "iommu=pt", but did try with this removed, still
got the errors (I think amdgpu driver uses the IOMMU even when it's
set to IOMMU=pt though.). See the attached log for some very odd
"[Hardware Error]" messages that were logged on one test run. I think
this was when I tried to run firestorm (second life viewer) -- that
had a large pause then opened to a black window.
Per Google, I see there was a bug like this that turned up in kernel
5.14.15 but fixed in 5.14.17. See
https://gitlab.freedesktop.org/drm/amd/-/issues/1770
Thanks!

Fix:
upstream commit afd18180c070 ("drm/amdkfd: fix boot failure when iommu is
disabled in Picasso.")
Patch was included in the Impish kernel in -proposed (5.13.0.24.24)
from an upstream patch set. multiple confirmations the problem is
resolved with the kernel in -proposed.
