Sorry, I meant to respond. This is more than likely a SCSI emulation
error rather than a kernel error. I've seen the error a couple of
times, but I don't have a fix for the issue yet as I don't have a
reliable way to reproduce the error. If you have an easy way to
reproduce the bug, I'll see if I can figure out a fix.
