Latest news after two more weeks of using 12.04: - Crashes became less frequent but were indeed not gone both with the 3.4 as well as with the latest 3.2 kernel - Apport no longer 'detected' any of the crashes so I was unable to send out any reports about them (regression in Apport?) - Since the situation was unworkable for me and no solution is in sight, I have installed a separate video card. I don't expect the crashes to return now. If they do, I will of course let this know.
One funny detail is my laptop - it's running rock-solid with 12.04 even though it also has an i5 (m520 instead of 2500) with an i915 integrated GPU. Googling around suggests that this CPU is of the 'old' Nehalem architecture instead of Sandy Bridge, which would really pin-point the problem to Sandy Bridge CPU's. It's also running a lower res though. I will notice next week if this makes a difference when I get back to work (it's connected to an external 1920x1200 monitor there). -- 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 with WARNING: at /build/buildd/linux-3.2.0/drivers/gpu/drm/i915/i915_drv.c:413 __gen6_gt_wait_for_fifo+0x94/0xa0 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+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
