intermittent system crashes supposedly caused by intel xorg driver

[okubax]

Binary package hint: xserver-xorg-video-intel

Started about a week ago and now, it's really becoming a "pain in my ass". My Ubuntu Jaunty system now crashes/hangs/soft-freezes(whatever) more than 6 times daily. First I thought it was becuause of the new intel driver that I installed after following some steps mentioned on Ubuntu Forums, after which Ireverted back to the original Ubuntu Jaunty intel driver and then the nightmare really started. No matter what I am doing, the system always crashes even when it is idle !. So I thought it was time to look at my system logs to see what the hell was going on. I found out that the evry time that my system crashes, it always logs an error about this: "drm:i915_getparam". Guess it had something to do with intel drivers

the log extracts above are just some of the weird erros I get when my system crashes. Don't know what's going on ??

I experienced the same behaviour during the last 2 days. Now I did an aptitude safe-upgrade with the result, that more and more system error similiar to the ones above show up. I, too use the Intel-driver on an Lenovo T400 notebook.

Right now I bootet to an Live USB-Stick, without any errors arising in the system log so far, so it looks, as if my installation is corrupt.

I also did an memtest86 test of the system, which showed no errors.

Attached is the output from dmesg, taken until X crashed due to multiple xfce-applets failing.

Changing the display adapter does seem to help. The T400 has an additional Radeon card built in, which i enabled in the bios. Using the radeon driver, i could not observe the errors occuring with the intel card.

This sounds like a really common freeze issue we had with -intel on Jaunty. The freezes are largely solved in Karmic, unfortunately we've found backporting the fixes to Jaunty is essentially impossible due to the breadth of the architectural changes involved. Since I'm fairly sure this is solved in Karmic I'm closing it as fixed; feel free to reopen if you can reproduce the issue on Karmic, in which case you should follow the directions at the following link to collect debug data needed for the freezes:
