Router jsem si připojil přes sériovou konzoli … s připojeným tunerem se neustále dokola restartuje. Už samotné zapojení tuneru je pro router “smrtelné”.
Původně jsem ho zkoušel s modulem kmod-dvb-usb-cxusb ten způsobil kompletní freeze a recovery ze snapu. Po odebrání modulu přes rmmod, odinstalaci a instalaci kmod-dvb-usb-dvbsky se dělá tato smyčka.
Má někdo nápad kudy dál?
