I'have tracked down an annoying problem I have with latest Compaq deskpro
with pentium II cpu's at work. (Deskpro 6000/6266X)
The problem: Linux will keep on rebooting right after executing the
init_bh "call" (macro defined in include/linux/interrupt.h) in
drivers/char/keyboard.c:kbd_init.c
at boot time. You'll say "Don't buy compaq crap" and i'll reply "yeap,
but my boss love compaq crap..."
The keyboard controller used on this board is a NS PC87306.

I spent two nights commenting out pieces of code in the kernel,
(starting from where the computer auto-rebooted on startup) rebuilding,
rebooting the Compaq from floppy, and so on, being able to narrow down to
this init_bh.
But now, I'm not kernel guru enough to understand what's happening in
init_bh. This macro seem really simple and doesn't mess in any way with
registers of the keyboard controller, or irq etc..
Could someone help me make linux boot on this box? I don't want to see
NT running on that one :)
Cheers.
