Description

Please either attach the whole dmesg or include the full WARN. Now tell us more about the freeze since that is not directly related to that warning. Created attachment 103316 [details]
All dmesg output
More precisions:
the cursor crash appears even more frequently (as you can see in the dmesg) such that the system becomes unusuable and need to be restarted: the bug appears only after a while maybe after wake up from suspend to ram.
I can send you more info if you want to.

Another dmesg output when system is freezing (or cursor always blocked, screen not refreshed)
I can reproduce this bug and am working on a test case and a Kernel fix. Created attachment 103369 [details] [review] Possible fix Hi Can you confirm this patch fixes your bug? It fixes the bug I can reproduce... I also implemented a test case to reproduce it: http://lists.freedesktop.org/archives/intel-gfx/2014-July/049481.html Thanks, Paulo Hello all, Many thanks for your patch. I have to test it now. Since it is the first time I report a kernel bug, I do not really know the good practices to test the patch you send me. Which documentation / tutorial / procedure do you advice I follow ? Many thanks in advance for your comprehension. Best regards for you and your works.
