I just filed three more instances of this bug, one with the exact same result as in this bug (bug 978219) and two bugs (one pair) which are related to a single 'almost' crash: bug 978221 and bug 978222.
I hope these shed more light on the matter. Also, I've attached the i915_error_state which is the result of two 'false' lockups (the first as described in bug 978221 and 978222 and the second occuring while I was entering this comment). If you also need the i915_error_state of when the machine was 'truly' frozen, let me know. ** Attachment added: "result of 2 'false' lockups" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/975083/+attachment/3041744/+files/i915_error_state.log -- 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/975083 Title: [sandybridge-gt1] GPU lockup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/975083/+subscriptions _______________________________________________ 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
