From: buhrow%lothlorien.nfbcal.org@localhost (Brian Buhrow)

        Hello.  I've been running NetBSD-3.x and NetBSD-4.x  systems using the
Sunfire X2200M2 servers for just about a year.  A whileago I tried using MP
kernels on a couple of the X2200 machines, and found that I got a
continuous interrupt storm which made them run extremely slowly.  More
recently, I found that I could run MP kernels fine on some of the machines,
but not others.  The difference between the ones which work and those that
don't seems to have to do with the ACPI system on the motherboard.  I've
been able to identify the ones which will work by the ACPI OEMID string in
the boot messages, see below, but don't know how, if it's even possible, to
upgrade the ACPI code on the older boards.  I've tried upgrading the BIOS
on the older boards, but it doesn't appear to change the OEMID string in
the boot messages, and it doesn't change the behavior of the machines that
have trouble.  They still get bogged down in interrupt storms, while the
newer revisions of the ACPI code work fine, and MP kernels run beautifully.
        Below is a diff of the boot messages on a working MP system versus a
non-working MP system.  My questions are as follows:

1.  Is this a known bug with some ACPI implementations, and has it been
fixed in the 4.x code?  Or, can it be easily fixed?

2.  Should I be able to flash these motherboards in such a way as to be
able to upgrade their ACPI subsystems  to a working revision?

Note: Version 704 of the ACPI system on these boards doesn't workin MP
mode, but 807 does.

Thoughts?
