Hi.
I had two drivers stop working in 2.6.31 that were working fine in 2.6.30. 
They are iwlagn and sky2. If i pass acpi=off to the kernel, they work as 
expected.

This is what is output from the drivers when they don't work:

[    7.878413] sky2 driver version 1.23
[    7.884402] sky2 0000:07:00.0: enabling device (0000 -> 0003)

Attached are the complete dmesg and lspci -v output.
This is using the SuSE repos version of 2.6.31-rc5 but i tried the vanilla 
kernel packages and the same happens.

Anything i can help with to resolve this, let me know. This bug took out all 
my onboard networking so i'm now using a USB wifi stick.

Thanks
