FreeBSD scorpio.seibercom.net 7.2-STABLE FreeBSD 7.2-STABLE #0: Wed Nov  4 08:21:40 EST 2009     gerard at scorpio.seibercom.net:/usr/obj/usr/src/sys/SCORPIO  i386
>Description:
For approximately a week now, when using Firefox, my system will freeze up for approximately 10 seconds, the crash and reboot. It does not happen every time, however. There also does not appear to be any pattern to why the system crashes.

I have attached the "info.4" (renamed info.4.txt) file. I have the "bounds" and "vmcore.4" files if you need them.
