You should smack yourself upside the head, for rebuilding a distro
kernel and complaining about a known problem that was already resolved
instead of googling about the problem and simply downloading the
updated driver.  F11 is known to be buggy, I can't explain why Fedora
themselves haven't yet absorbed the fix.

Meanwhile, for best results, use the following driver repository --
the bug is fixed here, along with additional tuning performance
improvements:

http://kernellabs.com/hg/kernellabs

For instructions on how to use mercurial to install the drivers, see
the instructions here, but use the above repository that I pointed to:

http://linuxtv.org/repo

Of course, you can use Mike Isely's standalone pvrusb2 driver, but it
does not install the updated tuner / demodulator components.  I
recommend the kernellabs tree.
