This is due to a bug at the tuner core.
> After seeing you patches at the beginning of last month I installed the recent drivers at the time and applied your patches. The frequency out of range error went away but the only sound I got was static. I then discovered the frequency is out by 2.7MHz, so if I want to listen to 104.9 I need to tune the radio to 107.6.
Try to remove Thierry xc3028 patch. His patches were applied already at the main tree
(I applied them very early today).
