Description fbibsd 2000-04-09 21:40:01 UTC

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:

Fix: 

unknown
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.

Again, no more complaints of this happening in later versions.
