Please file a sighting here:

http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
Category: config-interrupts

Please note if this has always not worked, or if a previous version of Linux worked.

Please attach the dmesg and /proc/interrupt from the acpi=off boot;
and the same for the boot with no boot parameters.

Please attach a single copy of the output from acpidump,
and the output from lspci -vv.

thanks,
