http://bugzilla.suse.com/show_bug.cgi?id=1004048 http://bugzilla.suse.com/show_bug.cgi?id=1004048#c1 --- Comment #1 from David Disseldorp <ddiss@suse.com> --- I tried a few suggested workarounds using X11 'Option "NoAccel" "True"' and booting with i915.semaphores=1 , but didn't have any luck in both cases. I'm now running 4.8.0-2.gb49afc4-default from Kernel:HEAD and haven't hit this since then. Given that this bug locks-up the system completely, I'm not going to attempt to bisect the issue. -- You are receiving this mail because: You are on the CC list for the bug.
