Bug ID: 109526
Summary: [CARRIZO] amdgpu fails to resume from S3, atombios
stuck executing C554 (len 629, WS 0, PS 0)
Product: DRI
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: johannes.hi...@datenkhaos.de
there is already a similar report at kernel bugzilla, but nobody took notice:
https://bugzilla.kernel.org/show_bug.cgi?id=190971
It's a kernel bug, first seen with linux-4.20 on my Carrizo. I don't have a
testcase for reproducing, so it's hard to bisect. Sometimes it happens multiple
times a day, with every suspend-resume cycle. Sometimes the machine works for
several days with at least two suspend-resume-cycles per day.
