Comment 38 for bug 270798

You can add my machine too - noapic seems to put it right, as far as I've tested. Lenovo W700, Jaunty. Also happens with Fedora 11 pre-release. I'd guess it's also related to this outstanding kernel bug, looks like something they broke a short while ago....

It was happening before the nvidia driver was even installed, and after - definitely interrupt related since keypresses, mouse movements - even inserting a CD cause it to wake up.
