Bug ID: 98020 Summary: Tonga agd5f 4.9-wip WARNING: at drivers/gpu/drm/drm_irq.c:1168 drm_vblank_put+0xaa/0xb0 Product: DRI Version: DRI git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: adf.lists@gmail.com

R9285 on current agd5f drm-next-4.9-wip I get 00s of below when running videos/games full screen.

The last version of the branch didn't have this issue.

No bisect, but a couple of reset --hard seem to show it started with one of the recent merges.
