--- Comment #32 from Mitch Humpherys <mitch.spec...@gmail.com> ---
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

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 <bske...@redhat.com>
Cc: <sta...@vger.kernel.org> # 4.19+
I can cherry pick just this commit on top of 4.19 and I get a stable system.
