Is amd-staging-drm-next stable for you?
It seemed stable before the changes you pushed this morning. :) As of
cfb6dee86711 "drm/ttm: add transparent huge page support for cached
allocations v2", I get a flood of
[TTM] Erroneous page count. Leaking pages.
in dmesg while running piglit, and it eventually hangs[0].
Great, going to take a look.
Anyway, unless anyone knows which commits from amd-staging-drm-next are
needed to make 1d00402b4da2 stable in 4.14, the safe course of action
seems to be reverting it (and ac7afe6b3cf3, which depends on it)?
The amdgpu_ttm_bind change should be fixed by "70a9c6b drm/amdgpu: fix
placement flags in amdgpu_ttm_bind". But I've assumed they went both
into 4.14.
Thanks for the bugreport,
Christian.
