Don't worry, I wasn't trying to talk you out of an ACPI bug report;
I just wanted to get enough specifics so I could see whether it was
something I could fix.

These messages also happen with 2.6.25, where the MPT Fusion driver
worked, so Kurk opened a separate bugzilla,
http://bugzilla.kernel.org/show_bug.cgi?id=11049
for them.
Yakui Zhao thinks the messages are harmless because they're
related to interrupt link devices that we don't use in IOAPIC mode,
and given that the driver works in 2.6.25, that seems plausible
to me.
Regardless, the messages are alarming and annoying. I'd like
to understand them better, but I'll pursue that in the 11049
bugzilla.
