Comment 41 for bug 399821

@Twig -- so this does not occur with 2.6.31-14.28, and does with 2.6.32-2.2. It would be helpful to try and work out whether it occurs on the latest Karmic kernel 2.6.31-17.54 in karmic-proposed. If so it would be handy to see which release inbetween that the issue occured. If no then it would be somewhere between 2.6.31 and 2.6.32, so it would be helpful to see which of the 2.6.32-rcN kernels work and which do not. Those can be found in the mainline kernel archive:

Please report any testing results here. Thanks!
