Essentially every 13.1 user with an rt3290 wireless device is affected by
https://bugzilla.kernel.org/show_bug.cgi?id=61621. The necessary patch has been
applied to mainline and backported to stable kernels. I do not know what
revision of 3.12 has the patch, but 3.11.8 contains it. Unfortunately, users of
openSUSE 13.1 only get 3.11.6, which does not have the patch.
If there is some major reason for not using 3.11.8, would it be possible to
cherry pick the patch. The mainline commit is
