The easiest way is to apply the patch and look for DRM_DEBUG_DRIVER messages. This is unlikely to fix the problem, but also can't hurt. We've only assumed new BIOS will fix the problem, but who knows. Especially if it's a 3rd party BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1041790 Title: [sandybridge-m-gt2] GPU lockup IPEHR: 0x0b160001 IPEHR: 0x0b140001 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1041790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
