Subject: [regression] e100: PCI wake-up handling rework causes "Error clearing wake event"

(Resending because of error in mail headers in previous attempt; sorry)

On my Toshiba Satellite A40 with 2.6.27-rc4/5 I noticed the following 
error in the boot log (not there with 2.6.26):
e100: 0000:01:08.0: e100_probe: Error clearing wake event

Bisection has fingered the following patch as the cause of the message.

commit eb9d0fe40e313c0a74115ef456a2e43a6c8da72f

    PCI ACPI: Rework PCI handling of wake-up

The test this error originates from in drivers/net/e100.c is old and has 
not changed recently.

Surrounding messages (full dmesg attached):
e100: Intel(R) PRO/100 Network Driver, 3.5.23-k4-NAPI
e100: Copyright(c) 1999-2006 Intel Corporation
e100 0000:01:08.0: PCI INT A -> GSI 20 (level, low) -> IRQ 20
e100: 0000:01:08.0: e100_probe: Error clearing wake event
e100: eth0: e100_probe: addr 0xcffff000, irq 20, MAC addr 
00:08:0d:17:bf:f5

The NIC is:
01:08.0 Ethernet controller [0200]: Intel Corporation 82801DB PRO/100 VE 
(MOB) Ethernet Controller [8086:103d] (rev 83)
        Kernel driver in use: e100

Cheers,
FJP
