Rafael, this is a 2.6.30->2.6.31 regression.

Given that both the wired and wireless interfaces failed, I'd assume
that something went wrong at the bus level. Perhaps due to an ACPI
change.
Could the sky2, iwlagn and ACPI developers please take a look, offer an
opinion as to where we should be looking?
Thanks.
