Comment 19 for bug 492392

Andy,
As far as I can tell, this issue has been fixed upstream in the stable tree, and the fix is already in the ubuntu kernel:

http://bugzilla.kernel.org/show_bug.cgi?id=14781

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=commit;h=b9e13497d8cdc40e74a4f14faaa255a0051bb1db

So there should be no need to disable powersaving for everyone.
