--- Comment #11 from Maarten Lankhorst bugs@mblankhorst.nl --- Created attachment 163871 --> https://bugzilla.kernel.org/attachment.cgi?id=163871&action=edit Restore old fence wait behavior
Ok the only difference I can see is the fence wait function being different in that commit. The new one should be correct, so lets see if it that's what causes it, or if it's the introduction of timeouts in ttm.
Does this hack change things?
