Hi, Sorry to but in like this but I'm suffering from the same kind of deadlocks with nouveau... The really odd thing is that i could boot some -rc6+ kernel without problems but it hung while playing video and then it refused to start properly again. Anyway, to quote Maarten: Ok that most likely means the interrupt based wait is borked somehow, so lets find \ out why.. I fear that this happens because of a race in the interface, so my first attempt will \ rule out abuse of the nvif api by nouveau_fence.c Can you test below patch with the default wait function? --- I tried the patch, straight on Linus' master and it didn't change anything for me :( _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
