janmartin, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue. Please do not test
the kernel in the daily folder, but the one all the way at the bottom.
Once you've tested the upstream kernel, please comment on which kernel
version specifically you tested and remove the 'needs-upstream-testing'
tag. This can be done by clicking on the yellow pencil icon next to the
tag located at the bottom of the bug description and deleting the
'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream-VERSION-NUMBER', where VERSION-NUMBER is the
version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream-VERSION-NUMBER', where VERSION-NUMBER is the
version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why
specifically you were unable to test it and add the tag: 'kernel-unable-
to-test-upstream'.

Please let us know your results. Thank you for your understanding.
