Yes there is.  At this point, however, there are no drives attached.  I
am beginning to wonder if the problem has to do with the driver
thinking there are drives because the multiplexer is there, expecting
responses from the drives that will never come, and not handling the
timeouts gracefully.

For more information, I have posted some files at

        ftp://biology.nmsu.edu/incoming/NetBSD/

The files include kernel configs, boot logs with backtraces, and a patch
to the source tree just to get build.sh to make all the kernels.  The
README file also has a brief description of the hardware.  I hope this
helps.

Cheers,
Brook
