So I tried JH's solution and it didn't work. Just to make sure I'm not skipping a step here's what I did:
1) after initial GPU hang, I logged in via ssh, edited /etc/apt/sources.list 2) added the gpg key 3) sudo apt-get update 4 sudo apt-get upgrade -u 5) restart 6) a few minutes after login, much less time than before, GPU hung again.. This time however I get a different error: [45381.436034] render error detected, EIR: 0x00000000 [45381.436868] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 28917 at 28544) [45383.488015] [drm:i915_gem_idle] *ERROR* hardware wedged [45384.613638] [drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware, good luck [45384.972012] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung So it looks like it's not the back cache this time.. I think it's because those drivers are nvidia and mine is not? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. https://bugs.launchpad.net/bugs/555573 Title: [g41] GPU hung: Failed to submit batchbuffer: Input/output error _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
