Indeed, I can reproduce your panic, using the current pkgsrc-archive from
ftp.netbsd.org dated 31-mar-2012.

The crash location is in pmap_activate() from m68k/m68k/pmap_motorola.c:

        pmap_t pmap = l->l_proc->p_vmspace->vm_map.pmap;:

vm_map seems to be NULL.

As this function is common to all m68k ports, can you reproduce the crash on
other m68k machines (I have just Amiga hardware here)? Maybe it has
something to do with the last kmem changes.

Also the patch suggested by Michael Hitch in
  http://mail-index.netbsd.org/port-m68k/2012/02/07/msg000319.html
had not yet been committed. Maybe it is related?

When I find some more time I may try to make a small example to reproduce
the panic.
