Description of problem:
Tar hangs in D state on tape write, using Adaptec AHA-3960D SCSI card and Dell
PowerVault 122T. I can't kill the process and can't 'ls /proc/[it's pid]/fd/'
Version-Release number of selected component (if applicable):
I'm using an FC3 system with kernel 2.6.11-1.14_FC3smp.
Tar accepts a "-b" flag for the size of blocks to use in writing and reading.
If I don't first set the tape drive to use a corresponding block size, tar hangs
immediate on invocations for read or write. When I do set the corresponding
block sizes, the behavior becomes infrequent, but happens after about a day of
Steps to Reproduce:
1. tar cf /dev/tape files
