Ah, yes.  I was thinking you had CAM_DEBUG enabled which is why you
were seeing this spew - but that's not the case.  This indeed should
be fixed and not just ignored.

Seeing the attributions on Alexander's commit, you certainly seem to
have a monopoly on controllers that exhibit this problem on FreeBSD.
:)

I believe the CAM_LUN_INVALID here should be fixed as well, similar to
the twa commit.  If you send me a revised patch I will commit it.

Thanks,
