Title:
[amdgpu] Several stability bugs in pre-5.17 kernels, e.g. on AMD RX
6600 XT
Status in linux package in Ubuntu:
Incomplete
Status in linux-hwe-5.15 package in Ubuntu:
Incomplete
Bug description:
Since updating to kernel 5.15 in Ubuntu LTS 20.04, I got several
stability issues with my AMD RX 6600 XT graphics adapter. I upgraded
to LTS 22.04 with the hope to be able to get more recent kernels, but
there are no HWE kernels and the GA kernel is still 5.15, while I
would expect it to be at least on kernel.org's recent stable kernel,
5.19.3 as of now.
These are the bugs that seem to affect me and other users of more recent AMD
GPUs:
https://gitlab.freedesktop.org/drm/amd/-/issues/1819
https://gitlab.freedesktop.org/drm/amd/-/issues/1871
https://gitlab.freedesktop.org/drm/amd/-/issues/1887
If you read the bugs, you find that people report kernel version 5.17
or more recent to fix them, which I can confirm: I started to run the
Ubuntu OEM kernel ( 5.17.0-1015-oem ), and thus far got a 100% stable
system.
So, I guess these problems will be solved with the next HWE kernel,
that is expected to be added to the Ubuntu 22.04 archive in October.
However, for current Ubuntu 22.04 or 20.04 HWE users, there is no
supported solution to get a stable system with various amdgpu
adapters.
