dmesg with lockup warning at the end
An amdgpu syscall, called by plasmashell, appears to deadlock randomly and
freeze X.org completely. Several graphics processes, plasmashell and X.org =
are
left stuck in D-State. Everything else continues to operate correctly,
including audio, networking, etc..
The issue seems to appear more frequently whilst running games, although I =
am
unable to find any particular pattern to it.
Running Arch Linux with a custom compiled linux-zen kernel, Mesa 17.1.4 with
Radeon RX 480. The issue has been around for a while and affects all 17.1.x
releases so far, however I am not certain for how long it has been around. =
The
issue is way too rare though for me to bisect the exact cause however.
Once I get another freeze I will see if I can get any userspace thread dumps
from plasmashell and possibly other processes as well as any logs containing
something interesting. (This may take anywhere from a few days to weeks due=
to
the random nature of the lockup)
(Also, just to clarify, this is not directly related to
https://bugs.freedesktop.org/show_bug.=
cgi?id=3D101294, this occured before and
after that issue being fixed.)
