In the ACPI submenu there are following options:

ACPI version features (1.0, 2.0, 3.0 - I have set it to 3.0, but I think
I have tried 2.0 as well)
ACPI APIC support (I have Enabled)
ACPI SRAT table (Enabled)
ACPI OEMB table (Enabled)
Headless mode (Disabled)

Then there is a MPS option in a different submenu (I have 1.4, but I have
tried 1.1 as well).

Another APIC related function is in the southbridge setup:
Hide XIOAPIC PCI function (I think I have it disabled[*])

[*] I had to put this box to production use (even with one CPU visible),
but I will have an identical box available in two weeks or so,
so I can do more testing then.

: I guess that /proc/interrupts shows this system running in PIC mode?

Yes, of course.

Done, http://bugzilla.kernel.org/show_bug.cgi?id=7908
BTW, when trying to attach the dmesg output to the bugzilla entry, I've
got the following message:

I think the dead.letter message should not be there :-)
Apparently, this bugzilla does not have a "bugzilla" category.
Where can I report this?

: Any chance you can see if Windows finds multiple processors on this board with this version of the BIOS?

I can try this in two weeks or so.

: ps. after you get the acpidump for the failing system, check for a BIOS update.

In the pervious mail I wrote:

So AFAIK there is no BIOS update available.
