I just put a new kernel on ftp.netbsd.org:
	/pub/NetBSD/arch/sun3/netbsd-gen.gz
If you are using the previous (#137) you should update.

This includes some recent fixes, and some new ddb commands:
  machine abort:	Drop into monitor via abort (allows continue)
  machine halt: 	Exit to monitor as in halt(8)
  machine reboot:	Reboot the machine as in reboot(8)
