This is an AML run-time error from a PCI Interrupt Link
trying to find its "Present Resource Settings" --
ie. the current IRQ for a programmable IRQ.

Please open up a bug report here:
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI

For 2.6.20.stable and the latest 2.6.21, please
build with CONFIG_ACPI_DEBUG=y, and
attach the complete output from dmesg -s64000
and paste the /proc/interrupts.

Also, please attach the output from acpidump
and lspci -vv taken from either boot.

thanks,
