Bug ID: 109649
Summary: [raven] gfx ring timeout when running clover apps
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: jv...@scarletmail.rutgers.edu
This is a regression in 4.20.x, the same userspace works ok on 4.19.
I could bisect, but it's my main machine so I can't quite dedicate the time,
any hint would be appreciated.
The kernel is booted using iommu=soft. full iommu hangs on boot, and noimmu
disables the wi-fi.
Dmesg:
> [ 702.207054] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout,
> signaled seq=1340, emitted seq=1342
> [ 702.207061] [drm] GPU recovery disabled.
