Xorg.0.log

Description of problem:

I recently upgraded to fedora13.  Ever since then X locks up every few
hours.

This is displayed in the Xorg.0.log file:

[176146.816] [mi] EQ overflowing. The server is probably stuck in an infinite loop.

The machine OK (one can log in with ssh), but X is unresponsive.
Killing X and restarting instantly prints the infinite loop
message, so the problem seems to be at the hardware level.
