Ok. As you're getting signals with high symbol rate, it were less likely to
have troubles there.

That also means that the patch didn't introduce any bugs, so I'll likely
apply it, as this way is better than before.

As you said that you weren't experiencing any issue with a previous kernel,
I suggest you to do a diff between cx24123 on the version where everything
is OK with the current one, and post here. We can then try to detect where
the issue was introduced.

Mauro.
