I'm still able to reproduce this bug, but it's gotten much harder to do after updating from Gnome 3.2 to 3.4.
I updated my kernel and userspace and on Gnome 3.2 start up, the GPU would reset completely reproducibly. I updated to Gnome 3.4 and the GPU no longer hangs on reset, but after a long time of use, I will get dropped MMIO writes and the GPU will reset. I think I've had to leave the system on for more than a day to see this. I tried Ben's 450mV work-around, but it didn't help since my system wasn't affected. I tried the "drm/i915: Fix GT_MODE default value" patch, but it didn't help (my system did /not/ have the doc-suggested bits set in GT_MODE). I tried to update my BIOS (from v1.50 to v2.10) but my system's chipset is revision B2 which is apparently too old to update with a v2.10 BIOS that supports Ivy Bridge. I have not tried disabling contexts yet, but since I have experienced this RC6 bug ever since RC6 was first enabled by default (~kernel 3.3?) and contexts were only implemented in 3.6, I highly doubt they're involved. I'll test with contexts disabled in any case. What more can I try? It's significantly more difficult now that Gnome 3.4 doesn't reliably trigger the reset. -- 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/1020733 Title: [sandybridge-m-gt2+] GPU lockup IPEHR: 0x78170003 Status in X.org xf86-video-intel: Incomplete Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: I had a projector connected, suddenly everything exploded.
