I am using the SCSI emulation for a Seagate STT20000A, ATAPI TAPE drive. After a few hours it timed out. Problem solved. Jeffrey Quoting Jeremy Buchmann <jeremy@wellsgaming.com>:

mt is stuck in D - uninterruptible sleep, according to top. I tried a retension 8P and now it's stuck. killall -9 mt won't stop it. Is there anyway to kill it short of rebooting?
I had the same problem when my backup drive froze during a backup. Any further attempts to write to that drive resulted in the process going into DW, which is similar or the same as D, IIRC. Unfortunetly, I ended up having to reboot...I wish someone could fix that.
