I'm trying to run NetBSD 1.0A (as of yesterday or so) on my Sun 3/75
(but with an si SCSI controller rather than an sd controller).

My NetBSD root disk is an old 140Mb Sun shoebox with target 1.  I
created file systems and extracted all of the sun3 tarballs from
ftp.netbsd.org onto this disk.  (I normally run SunOS off of the disk
on target 0, and it's a pain to change the SCSI id on the shoebox.)

So I recompiled the kernel from -current using a slightly modified
GENERIC config file (I commented out "options GENERIC" and changed
"swap generic" to "root on sd1 swap on sd1").  Booting this, I get:

after which the machine hangs. 

What could be wrong, and what should I do about it?

If I get into the debugger and do a "ps", init seems to be running,
but I'm not sure what else could be going on.

thanks,
