FYI, I thought I'd update the list. We tried about everything, 
including new hardware.  The problem went away completely when we 
switched off LVM and just started using RAID.  We're left with less 
flexibility in adding new drives, but at least the system doesn't crash.

LVM + ext3 + BackupPC = *boom*
