and after cvsuping to source from Sep 17th, clearing out all those
locations, rebuilding/rebooting, using the machine for a few days it
paniced again with teh same symptoms (after resuming from suspend the
hard disk was pegged with no obvious process using the disk, machine
mostly idle other than a chunk going to system. Mozilla using some
userland cpu time. Kill mozilla, machine panics).
This time before I did anything else I ran top and waited about 20
mins for something to change, nothing did. I watched top as I killed
mozilla and saw kldload appear ... then it paniced.
Since I've recently been having problems with the an driver not
reattatching after a suspend/resume cycle I've been kldunload and
kldloading if_an automaticly on suspend/resume, I'm assuming that
something there is what is provoking this panic.
I've checked that if_an.k and my kernel are form the same time and the
same source after my last cleanout;
