  The NetBSD 1.1 SCSI drivers included support for disconnect/reselect.  If
I remember correctly, synchronous transfers were enabled by default in 1.1,
which was a change from 1.0.  Either one of these changes could possibly
be causing problems.

  The synchronous transfers can be disabled by specifying "-I ff" on the
loadbsd command.  Disabling disconnection support has to be done by changing
the driver, either by modifying the source or using binpatch to change the
controlling variable (_sbic_enable_reselect).
