All bacula daemons are running in user mode and only the FD is running 
as root. A hard lock like this means something is amiss at the kernel 
mode level. You could try backing up to a directory on SCSI/SATA/IDE 
disk as a test. If all works as expected when backing up to the non-USB 
drive, then maybe something is wrong in the way USB is being 
virtualized/configured.
