       That "biodone already" panic is definitely related to the specific
drive mechanism (and controller board) being used.  I got lucky for
Christmas and found a brand new 3.5GB hard drive under the tree, with a DEC
RZ74(C) mechanism inside.  I immediately loaded NetBSD on it, and now the
only time I get the XS_BUSY response status (which leads up to the panic)
is during startup configuration.  Once its up and running, I don't see that
status unless I try something like hfs which goes off and probes the bus
and drives again.

Yep - I'm gonna get the -current tree again and see what I can do with scsi
stuff.  Now that I got some room on my disk, I can keep both trees on-line!
