bouyer 3dc7dba078 It seems that the 1010-33 has a bug: it sometimes generate spurious SCSI gross
errors for narrow transfers after a reselect. FreeBSD sym driver has a comment
about this, but their workaround (disable SCSI gross error reports) doesn't
work for me. Instead dissallow disconnect if the target is not wide
(FreeBSD doens't allow disconnect until the target has been fully probed, which
is why they may not have noticed my problem).
