Hello Ethan.  

Sorry you are having troubles.  I had troubles getting my Sun 3/80 to use
netBSD.  In the end, it turned out to be improperly allocated partitions.  I
don't know if this is related to your problems or not, but there seems to be
some serious lack of documentation in the area of partitioning disks.  I
found out that the installation was getting to a point where it was
overwriting data in a partition that overlapped my swap partition (or some
such) and I think I may have been getting errors similar to the ones you've
mentioned.  It's been awhile since I had this problem and I eventually got
it straightened out, and now my machine has been fine for the last 10
months.  I'm tempted to upgrade to 1.3.2 and see what's new, but I'm also
somewhat apprehensive of the whole process.

Make sure that your partitions are sane.  I don't remember what I did
exactly to screw mine up, or what I did to fix it so I can't be of much more
help.  I can only show you what the "edlabel" dump gives for my partition
scheme:

        type_num: 4
        sub_type: 0

Hope this helps.
