Bug ID: 216119 Summary: 087451f372bf76d breaks hibernation on amdgpu Radeon R9 390 Product: Drivers Version: 2.5 Kernel Version: v5.17+ Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: h.judt@gmx.at Regression: No
This is a problem with amdgpu only, as I did not experience this on my other machines, and caused by [087451f372bf76d971184caa258807b7c35aac8f] drm/amdgpu: use generic fb helpers instead of setting up AMD own's https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
Reverting this patch makes me a happy amdgpu user with working hibernation again on Linux 5.18.3.
Note I did the bisect on the stable linux repo, but that shouldn't matter.
