Comment 74 for bug 1165433

I managed to find one more bug report similar to this one. So now there are at least four bug reports (including this one) here in Launchpad on this problem:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189998

https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1256811

Anyway, if these are about the same bug that I think they are, the bug has now been completely fixed in kernel version 3.14, though kernel version 3.12 included some of the fix. Also there was one previous fix that is also needed that I think was backported to stable before 3.12.

I think I manged to list all the necessary commits, Here are links to the commits, in case they need to be backported:

The first fix (pre 3.12?):
