I have a problem with an ncr810 controller. The machine often hangs while I take backup. The machine is a Dell Omniplex 590 (startup messages at the end). Is this a known problem that is fixed in the latest SNAP release? (Or maybe a problem with the HP DAT drive?) What happends is: I started the backup at 10:20. It usually take 30 min. When these messages start showing up the scsi subsystem usually is about to hang. Mar 29 10:33:23 abserv kernel: st0(ncr0:4:0): phase change 6-7 1@306c4 resid=1.
