This has been reported a few times already -- probably the same thing as bug https://bugs.freedesktop.org/show_bug.cgi?id=83550 Sorry, no resolution as of yet. If you could verify that the commit that got bisected to in that bug indeed causes your problem, it would be nice to have before and after logs from a kernel compiled with NOUVEAU_DEBUG set to 7 (spam) booted with nouveau.debug=trace,PDISP=spam . That should hopefully help isolate the issue. (Don't use a kernel with NOUVEAU_DEBUG set that high for daily use -- it introduces a ton of debug code everywhere.) If the commit that got bisected to in the bug is not the cause of your issues, you'll need to do your own bisect.
