My system is Debian Testing, Amd64.
# uname -a
Linux dcr64 3.2.0-2-amd64 #1 SMP Tue Mar 20 18:36:37 UTC 2012 x86_64 GNU/Linux
(I have this problems for a long time ago, and with a others kernels)

Hi from a long time ago, I have a problem with Xorg, it crash and have to login
with another computer with ssh and "killall -s 9 -I xorg" to get X works again.
When crash, CTRL+ALT+Fx don't work. Crash with firefox, or with Abiword, or
only with gnome desktop.

[mi] EQ overflowing. The server is probably stuck in an infinite loop.
