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: jv356@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:
