Since the affected maschine is not reachable via SSH, I just dumped the error state every second (while [ 1 ]; sleep 1; do cat /sys/kernel/debug/dri/0/i915_error_state >> error_state; done) and deleted all the "no error state" lines from the file before the actual error dump after the crash. As it turns out, the error state is all zeroes (I do not expect this to be helpful):
$ hexdump errorstate.dump 0000000 0000 0000 0000 0000 0000 0000 0000 0000 * 0000150 0000 0000 0000 0000 0000 0000 0000 000a 000015f I expect the last byte to be the newline inserted from the shell. ** Attachment added: "errorstate.dump" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1176647/+attachment/3684114/+files/errorstate.dump -- 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/1176647 Title: Random Xorg freezes occuring hours after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1176647/+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
