Bug Description

SRU justification:

Impact: The mentioned change by upstream (in the Karmic release code) caused regressions for the detection of some devices.

Fix: "pci: increase alignment to make more space for hidden code" which comes in through 2.6.31.6 resolves the issue and allows affected devices to be detected again.

Just opening a bug in launchpad to keep this on our radar and also track the issue upstream:

http://bugzilla.kernel.org/show_bug.cgi?id=14402

https://lists.ubuntu.com/archives/kernel-team/2009-November/007770.html

The Atheros ath9k module is not working with [testing]-kernel 2.6.31.1 on an
Acer Extensa 7630EZ. Downgrading to 2.6.30.x solves this problem

> OK great, now please checkout a clean 2.6.31.5 branch:
