	Same here. Hung for me after:
root filesystem type: ffs
<hangs... I'm guessing at swap config>

	I wrote down a little more... I'll add ;-)

	Last kernel I have that works RELIABLY is this one:

NetBSD 1.3F (BRAHMS) #1: Mon Jul 13 06:53:37 PDT 1998
    sammael@brahms:/usr/src/sys/arch/mac68k/compile/BRAHMS

	I might add, this is from sources supped last night, plus a fresh
config (just to be safe), on a Quadra 630.
