Symptoms: total lockup of X, Xorg pegged at 100% CPU time, LEDs don't 
work, keyboard is usless. SSH in allows a clean shutdown, about 50% of 
the time.

About 50% of the time, this is last line printed in Xorg.0.log
[mi] EQ overflowing. The server is probably stuck in an infinite loop contains full dmesg, xorg.conf, Xorg.0.log, 
pkg_info of X/GL/Mesa bits and kernel config.

Similar issues here.

Triggers:  Opening Libreoffice, moving an image from firefox to pidgin, 
gimp or similar, using GQview, or similar.
Opening Libreoffice results 100% lockup, instantly. Hardware 
acceleration is off in both firefox and Libreoffice.

This has been going on since at least August and no one's been able to 
figure anything out either on the forums, or IRC.
Maybe someone on the lists here might have an idea.
