La scheda e' una Hauppauge Win TV su bus PCI, ti passo le linee di dmesg:

allora con tail -f /var/log/messages leggo i seguenti errori

con l' uso diretto alevt continua a mostrare le pagine televideo,
se alevt viene concluso e riattivato da un programma in perl che completa un ciclo di
analisi dati di alcuni minuti dopodiche' si riavvia

system ("alevt-cap -timeout 400 -name /gp/tlv/%s  @PgAz @PgIn @PgVl @Info");

l' acquisizione cade al riavvio ed alevt-cap non cattura piu'.
Il problema e' raggirabile con il riavvio contemporaneo di xawtv che
reinializza il sintonizzatore per alevt ma non la trovo una soluzione
decente ed utilizzo per ora il vecchio kernel

Ho recuperato un 2.6.15: appeno ho tempo lo compilo, lo provo e ti informo.

Porta pazienza perche' dire che sono pensionato e' un eufemismo e tempo
libero ne ho poco.
