ACPI Error message

[Glenn Meehan <glenn.meehan@optusnet.com.au>]

Hi,

I'm getting the following error message in my messages file:

Aug 18 18:47:00 bithynia kernel:     ACPI-0165: *** Error: No object was
returned from [\_SB_.PCI0.PX40.UAR2._STA] (Node c12f9300), AE_NOT_EXIST

kernel: 2.4.26
testing/unstable
Athlon 1.7
ASUS A7V266-E

What is causing this message?
How can I make it go away?

Thanks
