This patch in the linux-scsi archives should remove this badness
warning.
http://marc.theaimsgroup.com/?l=linux-scsi&m=106940008217622&w=2

It should apply cleanly to test10. I am just updating my view now to
test10 so I have not tested the patch on test10 yet.

I did not have it refreshed in time from James to include it in his
last update.

Confirmed, the badness and backtrace are no longer seen with this patch
applied.

Thank you,
Tony.
