Comment 17 for bug 349778

@joshual, if you could test the latest upstream kernel available that would be great (currently 2.6.30-rc8 at the time I've posted this comment). 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.
