This sounds more like a hardware problem.

There was an attempt to write beyond the end of the device because
everything in the file-system was getting trashed. I can read/write
the 5 year-old SCSI physical drive with no errors from both within
linux and through the Adaptec BIOS. This problem only occurs
when I attempt to truncate a file that is being written by another
task.
That SCSI error code doesn't sound like a reasonable one for the drive
getting a bad block address. The more typical one in that case would be
"Logical block address out of range", or maybe the catch-all "Invalid
field in CDB". "Peripheral device write fault", especially as a deferred
error (i.e. after the drive already returned a normal completion for the
data, and then is reporting the failure to actually write to the media
on the next command), really sounds like a drive problem.
And the kernel is supposed to trap those at the disk layer, like these
are saying it is, _after_ that error occurs:
