Kernel 2.6.13 repeated ACPI events?

[Justin Piszcz]

I have a box where I keep getting this in dmesg:

ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKD] -> GSI 5 (level, low) 
-> IRQ 5
ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKD] -> GSI 5 (level, low)

Anyone have any idea what could cause this?
