Hmm... exactly the same version I have here.

It used to have some issues with VIA and PCI, if you're using overlay mode
(this is the default, for xawtv).

This is due to some issues on buggy VIA bridges, when handling PCI2PCI data
transfers, used in overlay mode. If a PCI2PCI conflicts with a PCI2MEM transfer
(or a MEM2PCI), you may suffer data loss.

Are you trying to use radio just after a clean reboot, or are you experiencing
those troubles after running a video application that might be using overlay
mode?

Could you please send me your .config? I'll try to run the same config as you,
with the latest -rc.

Cheers,
Mauro
