Subject: Kernel 2.6.13 repeated ACPI events?

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

Anyone have any idea what could cause this?

I have a 3c905B nic that was sometimes enumerated up to 15 times (Intel
BX Chipset)
Plugging the thing out of its pci socket and back in always cured it.

maybe yours suffers from the same "bug" ?

I'm seeing repeated ACPI events too, but of the battery kind:

This is from the driver repeatedly calling pci_enable_device().
Can you instrument the driver to find out why?

At least in my case, I believe it's a BIOS/Device issue. The BIOS itself
lists the 3c905b several times before booting the OS. When this
occurs, neither linux nor windows can persuade the 3c905 to work.
Another thing, the motherboard in question is blacklisted by acpi
(Asus P2B-S)
