Bug#410386: Xorg segfaults randomly



Package: xorg
Version: 1:7.1.0-11

Hello,
In the past two weeks, Xorg seems to crash randomly on my Debian Etch
machine. It can work for an hour and up to 4 or 5 hours, and then
suddenly it crashes. It also seems to happen, when the screen changes.
When I am not working on this computer, it will not crash.

I asked this in mailing lists, forums and the debian IRC channel, and
finally was told all I can do is file this bug.

The hardware is, a Pentium 4 with a GeForce 6800 GS AGP video card.
I'm using this setup, for 4 months, without problems(*), it only
appeared recently, and I believe it was after upgrading some X related
packages (don't recall which).

This problem occurs with both the free nv driver and the proprietary
nvidia driver. I tried different kernels, tried downgrading to
previous version of Xorg (using snapshot.debian.net), but nothing
worked. It also should be noted, that running a live CD of Ubuntu
Dapper for a whole day, did not result in a crash.

(*) When I first upgraded to Xorg 7.1 from 7.0, I had the exact same
problem, because I didn't upgrade all packages to 7.1. Now however, it
does not seem to be this way, all packages are upgraded. The thread I
opened can be viewed in the following URL:
http://www.nvnews.net/vbulletin/showthread.php?t=78275

I get a back trace in the xorg logs:

If more info is needed, please mention that (Can I attach files here?
or do I have to copy their contents to the message body?).
