>Description:
	One of my machines hangs if I press ScrollLock when
	it runs /etc/rc and if I do not press ScrollLock again before
	/etc/rc.local finishes. If I press ScrollLock second time
	after /etc/rc.local has finished, syscons does not flush
	its buffer, system is stuck in a single user mode waiting
	for /bin/sh to exit. It won't: if I rlogin into the system,
	I see:

# ps -p 7 -wwl

    0     7     1 141   4  0     0    0 ttywai IEs+ con    0:01,14 sh /etc/rc autoboot

	Note, that kernel is alive, I can press Ctrl-T, I can
        break to DDB and see:

	It seems a kernel is stuck somewhere within ttywait()
	called from exit1(), file src/sys/kern/kern_exit.c

>How-To-Repeat:
	Note that I can reliably reproduce this but only on one
	of my machines. So I suspect that depends of local settings.
	
	So here is my /etc/rc.conf:

# This file now contains just the overrides from /etc/defaults/rc.conf
# please make all changes to this file.

	Then, here is my kernel config. I must note that I use
	this system for general testings and its world
	and kernel are built with "-O2 -march-pentium"
	just to find bugs.

 Here comes GDB backtrace. Note that after the first 'panic' and 'c'
 commands it does not write crashdump and does not reboot.
 It just sits idle. After the second 'panic' it works.
 The crashdump and kernel.debug are available on request (3.3Mb compressed).

 I can only reproduce this using old notebook running 4.11-STABLE.
 This old hardware has only 16Mb of RAM and small HDD

 Please close this PR.
