X server crashes at random on natty (intel)

[Gabriele N. Tornetta]

Binary package hint: xserver-xorg-video-intel

After the upgrade to natty I got some serious problem with the stability of the X server (everything was just fine in maverik, see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/787208). An update was released though that solved the main bug mentioned there.
Currently i'm getting random crashes of the X server after which I'm sent back to the login screen.

Here is my Xorg.0.log.old

Hey phoenix1987,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.
