>Description:
While trying to track fix / track down the boot problem in
kern/17870, I wanted to go into kernel configuration mode while
booting 4.0-RELEASE kern.flp.

If I keyed <spacebar> immediately after the Bios started booting from
the kern.flp, the system crashes with a repetitively scrolling register
dump.

When I retried the problem, I decided to wait a couple seconds after
the kern.flp was into its boot process (after the kern.flp displayed
the messages "/boot.config: -P" and "Keyboard: yes").  When
<spacebar> was keyed at this point, the following happened:

>How-To-Repeat:
1) boot from kern.flp, hit <spacebar> as soon as the boot starts.

2) boot from kern.flp, hit <spacebar> immediately as "Keyboard: yes"
is displayed, then give "-c" argument to boot prompt.

>Fix:
unknown

 System halted
 
 ...the system is as described in kern/17870, save that this time
 I had set BIOS "PnP aware os" from yes to no, and had interrupted
 kern.flp booting interactively as described above.
 
 I'll try a few more things in the system's BIOS and hardware inventory;
 I have a very similar system running 3.4-release, so it's probably either
 something very subtly different between the machine configurations
 or something truly 4.0-RELEASE specific.
