Comment 73 for bug 1112652

Just to make it clear again:

There is a fix, it will be in Ubuntu soon once the official kernel gets updated to 3.8.13, and *until then*, you have three choices:

* Wait until the new kernel comes
* Use the non-permanent hotfix described above
* Download and install the 3.8.13 from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13-raring/linux-image-3.8.13-030813-generic_3.8.13-030813.201305111843_amd64.deb

Personally, I find the last one most convenient.
