It sounds like you're hitting the known "system hangs with multiple
disks" problem that has been plaguing the NetBSD/Mac68k kernel since
about last September or October.  Several people are desparately trying
to find this bug, but so far have been unsuccessful.

In the interim, you can try building your own customized kernel.  The
bug seems to be triggered by a combination of the actual system
configuration and the kernel configuration.  Some systems crash or hang
with a GENERIC kernel, yet on other systems the GENERIC kernel works but
a customized (smaller) kernel crashes or hangs.
