Ever since upgrading to natty a couple days ago, I've been having problems with Xorg crashing. I got a traceback (already attached, gdmlog1), which suggested something related to pthreads, so I tried disabling hyperthreading and all but one core in BIOS. This reduced the frequency of crashing from about once per 10 minutes to once per 2 days. I don't know if it's specific to the intel driver, or if it is a more general issue.
As far as steps for reproducing the issue... I'm not exactly sure. This is a description of a typical session:
1. Log in via gdm. I'm using sawfish, with a custom Xsession.
2. Start a few programs. I ran xchat, chrome, midori, a few instances of dillo, and a few instances if urxvt (client/server mode, not independent instances).
3. Trigger a few window redraws, by changing desktops or moving windows around. I triggered these actions via key shortcuts, generally a few times in a fraction of a second.
Result: Once in a while, step 3 will cause an Xorg crash. The frequency increases quite a bit with SMP enabled (2 cores + HT, so 4 logical CPUs).
Binary package hint: xorg
