uname - messages log - dmesg

When I start Xorg with startx, I while I wait for previous programs to start I get a crash.  Been happening for a few builds now. (Randomly happens, About once every two weeks using laptop 10 out of 14 days).

After crash Xorg will exit out and I will be at gdb prompted.  I'm not a c programmer so I'm not sure about debugging with gdb.  I simply type "reboot".  On reboot laptop has not boot partition.  I have to do a hard reset with the power button for the laptop to come back on.

I have attached my logs:
 uname -a
 /var/log/messages (with gdb syscall)
 dmesg (right after hard reset is done)

Let me know if you want me to try a diff or new kernel build.
If someone has some gdb command I should run next time let me know.

The messages in dmesg and /var/log/messages are warnings from WITNESS, but they do not show any crash messages.  Are you sure it is a 'gdb' prompt and not a 'db>' prompt?
