One bug at a time! ;-) The rc6=0 bug seems much more nasty as it is affecting gen4/gen5 and seems to imply a deep underlying synchronisation issue (so could actually be all architectures, just more prevalent on gen4/5). The rc6=1 ilk bug really does look like a missing hw workaround, dying between a series of flushes on the render ring is a good indication that our hw interaction is at fault. rc6 is disabled by default on ilk because we had not yet managed to make it work reliably, that it still doesn't work makes it a lower priority bug to chase. However, given the closely linked bisection, fixing the common problem may indeed make the rc6 bug harder to trigger. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1081009 Title: [arrandale] GPU lockup IPEHR: 0x02000022 Status in X.org xf86-video-intel: Incomplete Status in “linux” package in Ubuntu: Triaged Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: These hangs started a few days ago in raring. There is no discernible trigger, it happens out of the blue. When it happens, the X screen stays uncorrupted, but totally freezes. The mouse cursor still works. I can switch to VT1 and work there. Killing my processes and restarting my session/X.org works up to some degree, but in the restarted session compiz behaves very erratic (lots of flickering grey rectangles, and compiz takes 100% CPU), so the only cure is to reboot. This happens several times a day.
