First, please 'reply-all' as I'm not on the list.
I've got a backup server that, every night, offloads things to a
secondary, USB attached hard disk. We've got two of these disks,
which we rotate so as to have a fairly recent off-site version, in the
event of a disaster. One of the two drives has start to cause the
backup server to core dump and reboot. The other works fine. I tried
taking the problematic drive and repartitioning and reformatting it,
but the problems persist.
Here is what I get from a kgdb:
ecrist at leopard:/usr/obj/usr/src/sys/GENERIC-> sudo kgdb kernel.debug /
