How interesting!  I "borrowed" that code (and hp300 too) for the
implementation of cpu_set_kpc() in the sun3 port and it gets the
infinite loop of "Process (pid 1) got signal 11" also, but only
on a machine with a fairly recent /sbin/init - another machine
with an older version of /sbin/init comes up just fine.

I haven't had time to debug it yet, but it is useful to know it
might be a common problem.  Please let me know if you fix it.
