Comment 4 for bug 761632

When I first installed Natty I got this error message on every boot up,
however the machine did not totally lock up. When I installed the
updates the next day, it booted normally without error messages and has
had no problems since. It looks like something in the updates fixed the
problem. Also, this laptop has had a hardware problem with the video
card, probably thermally related as it seems to work fine until you load
up the video card with say a full screen movie. When the video card
works hard and heats up I will get a video tear or vertical strips and a
HARD lock up requiring a hard shutdown and reboot. This problem on boot
did not cause a hard lockup and occurred on the boot when the video card
had not yet been doing much, so I did not think it a high probability it
was the same problem. Working fine after the daily Update Manager run.

Did not have similar error messages with Maverick, but did have the
occasional video lockup in both Maverick and Windows XP, which is what
led me to believe I have a thermal problem with the video card and not a
software driver issue. Those never threw an error code because they hard
locked the computer. Interestingly have not had a hard video lockup
since installing Natty, even when trying to push it with full screen
videos. May have to try Passmark or some similar video test in Linux.

Thanks,

Don
