Note that I have seen both: either no screen corruption at all or first slight signs of screen corruption (white rectangles around window frames) at the times of the hangs. The error messages that I find in /var/log/messages probably associated with the hangs (sorry, I can't get any messages ot of dmesg due to the hang...) seem to be the following: [drm:drm_mm_takedown] *ERROR* Memory manager not clean. Delaying takedown [drm:drm_mm_takedown] *ERROR* Memory manager not clean. Delaying takedown [drm:drm_mm_takedown] *ERROR* Memory manager not clean. Delaying takedown repeating any number between 3 to 5 times directly before the hangs (immediately followed by /var/log/messages starting over with my power-off machine restart). Will now move forward to test with the most recent stock kernel from the 3.6 series: 3.6.11-3.6.y.20121225.ol6 from the Oracle public yum playground to see whether this already is affected... :-( BR, Andreas</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
