Comment # 32
on bug 105319
from Mitch Humpherys
I'm also affected by this bug on Fedora 29. I hopped on the kernel mainline and started poking around and noticed that I see this bug on 4.19 but not on 4.20. So I bisected to find the commit in the 4.20 series that fixes the bug. The fix appears to be: commit 970a5ee41c72df46e3b0f307528c7d8ef7734a2e Author: Ben Skeggs <bskeggs@redhat.com> Date: Wed Dec 12 16:51:17 2018 +1000 drm/nouveau/kms/nv50-: also flush fb writes when rewinding push buffer Should hopefully fix a regression some people have been seeing since EVO push buffers were moved to VRAM by default on Pascal GPUs. Fixes: d00ddd9da ("drm/nouveau/kms/nv50-: allocate push buffers in vidmem on pascal") Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: <stable@vger.kernel.org> # 4.19+ I can cherry pick just this commit on top of 4.19 and I get a stable system.
