Re: scheda tv -- news
Mi sono scaricato ed installato gcc-3.2, quindi ho cambiato il link /usr/bin/gcc, che ora punta al gcc nuovo.
Dopodiche' ho ricompilato il kernel escludendo bttv (e solo quello).

La compilazione mi da' un sacco di errori per me incomprensibili.
Puo' dipendere dal fatto che non ho installato la patch per v4l? La patch e' per il 2.4.20, che e' gia' il mio kernel, per cui non l'ho installata.
