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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1081009 Title: [arrandale] GPU lockup IPEHR: 0x02000022 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1081009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
