If you install a Fedora kernel: yes.

I think: if you're able to reproduce the error easily, you should try
to bisect the patch which introduced the faulty behaviour. This would
only make sense with a vanilla kernel.

The first step would be to find a kernel which isn't problematic, and
the first one which is. Here's how to do it:

Alternatively, could you try latest mainline (3.17-rc7) and check if
the problem persists? Maybe it's solved there.
