I don't know if the automatic log attachement put a log in which we can see the error...

[Brad Figg (brad-figg)]

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help, we really do appreciate it.

Looks like a duplicate of bug 844957. Could you test the kernel in comment #20 of that bug?

[povniet (kevin-georgy)]

Ok the kernel patch posted here https://bugs.launchpad.net/bugs/844957 at comment #20 solved the problem. So seems this is a duplicate.
