> pci 0000:00:01.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

This is a "hard coded IRQ", rather than a programmable PCI Link,
so it doesn't look like this issue is related to ACPI
interrupt routing.

There are multiple PCI devices associated with IRQ16,
so it is likely one of them is pulling on the IRQ
and the others can't quiesce it.

The output from acpidump attached to the bug report will help,
as we can verify that the IRQ is associated w/ the
PCI devices listed below.

The dmesg is 2.6.35.11
Does any version of linux earlier or later work properly?

cheers,
