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@leopard:/usr/obj/usr/src/sys/GENERIC-> sudo kgdb kernel.debug / var/crash/vmcore.17 [GDB will not be able to debug user-mode threads: /usr/lib/ libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
