Hello,
You probably should increase timeouts in the stv0297 frontend driver.
Something like this works fine for QAM128 with my C2300 card:

You shouldn't be scared of tenfold increase in timeout loops as the loop
will exit as soon as the signal has been locked. For my case, the C2300
card normally tunes almost as fast as the older rev 2.1 card I own.
Best regards,
Mikko.
