Comment 39 for bug 209342

Adam: Have you tried a vanilla kernel? I just grabbed the intrepid sources and looking at the tags that exist it should be possible to bisect from a version of the vanilla kernel that shows the problem and the ubuntu tagged release that works.

Just an idea but if 2.6.22 works, 2.6.24 doesn't and 2.6.26 does work again, running bisect twice. First on 2.6.22-2.6.24 to find when the problem arises, then from 2.6.24-2.6.26 to find the fix should really narrow down the problem.

I'd help with this one but I don't have the hardware to test it on.
