sys/1386/i386/mptable.c rev 1.239 breaks boot.

[Ian FREISLICH]

Hi

I have a dual pII machine that doesn't boot with 1.239 of
sys/1386/i386/mptable.c.  It boots with this patch backed out.
Does anyone have any ideas beyond backing out this patch?

revision 1.239
date: 2005/01/18 20:27:24;  author: jhb;  state: Exp;  lines: +7 -1
If a valid ELCR was found, consult it for the trigger mode of ISA
interrupts that have a trigger mode of conforming.  This fixes problems on
some older machines that still route PCI devices via ISA interrupts when
using an I/O APIC.

This seems to be a case of breaking, rather than fixing older
machines.  It's highly reproduceable.  I mailed the author of this
commit over a week ago, but have not had a response yet :(.  This
is definitely a show-stopper, for me at least.
