>Description:
        When booting using boot -a to enter an alternate init, etc. My keyboard
        doesn't work.

        I traced the problem back to this commit

        http://mail-index.netbsd.org/source-changes/2008/12/29/msg214584.html

        That is, sys/kern/subr_autoconf.c:1.167

        revision 1.167
        date: 2008/12/29 13:40:11;  author: ad;  state: Exp;  lines: +6 -5
        branches:  1.167.2;
        Don't need to hold kernel_lock for most of this (and not into the 
swapper!).

>How-To-Repeat:
        boot my machine with -a
>Fix:
        Hold the kernel_lock in autoconf?
        Fix acpi?
