Comment 2 for bug 971204

Darxus, thank you for reporting this and helping make Ubuntu better. With the workaround removed, could you please post the results following https://wiki.ubuntu.com/DebuggingKernelBoot ? As well, if you could also please 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.
