Yeah, I doubt very much it's a backuppc issue, sorry if I may have 
implied that.  I'm fairly confident it's a ext3/driver issue.  But as 
this popped up when we began using backuppc I suspect it may have to 
do with the massive quantities of files and had hoped another 
backuppc may have encountered and solved it.

controller is onboard nvidia, using the sata_nv driver
drives are all Seagate ST31500341AS 1.5TB drives

drives are tethered by LVM to a 4.1TB single ext3 partition

Seems that centos reported bug also is using LVM, perhaps a tie, but 
it's ext3 that's crashing by the crash output.
