Hello.

>From my understanding of the kernel options:
	options	PANIC_REBOOT_WAIT_TIME=xx	# seconds before reboot
	options	KDB_UNATTENDED			# only required if compiled with kernel debugger
#	options	RESTARTABLE_PANICS		# should not be set

May be, you should also set kern.shutdown.kproc_shutdown_wait
in sysctl.conf to some reasonable time.
