Hi

I tried this today on an updated 11.10 and the problem seems to have disappeared. I'd say this one can be closed as not being possible to reproduce on 11.10
Best regardsMagnus

Magnus Olsson, thank you for reporting this and helping make Ubuntu
better. 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?
Can you try 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 run the following command from a
Terminal (Applications->Accessories->Terminal). It will automatically
gather and attach updated debug information to this report.

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

Also, if you could test the latest upstream kernel available that would
be great. It will allow additional upstream developers to examine the
issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once
you've tested the upstream kernel, please 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. Please let us know your
results.

Thanks in advance.
