    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.

    Ian
