Hi,

Starting with 8.3, I've been experiencing FreeBSD freezing up completely
after using firefox for a while. Thinking the problem would go away if I
upgraded to 9.0, I did that and I am still experiencing the same
freezing up. The mouse pointer freezes, the keyboard freezes (caps lock
light will not come on; Ctrl-Alt-F[1-10] does not work etc.). The only
way to get the system back is by pressing and holding down the power
button. 

The problem seems similar to: kern/163145


There is nothing in /var/log/messages to indicate a problem. Output of 
pciconf -lv and uname -a are at:

Anybody else experiencing similar freeze ups with 8.3 or 9.0 while using
firefox?
