NetBSD 1.3K (GENERIC) #261: Sun Mar 14 05:32:41 EST 1999

>Description:
        when rebooting netbsd without powering down, it does not successfully
reboot.  This occurs when doing a "reboot -r" for example.
It also occurs if I use "reboot -h" to get to the rom monitor and then
try to boot netbsd again.  If I do "reboot -h" and then boot and shutdown
nextstep, netbsd will then boot once again.

Something isn't getting initialized cleanly, I suspect.

>How-To-Repeat:
	
# shutdown -r now                      
Shutdown NOW!
shutdown: [pid 135]
#
