Greetings, I have an USB TV adapter identified as Hauppauge WinTV HVR 900 (R2) (card=18) and I'm using Fedora 11 with linux kernel vanilla 2.6.30.5 (the last stable as writing). Following the manual at http://www.linuxtv.org/wiki/index.php/Em28xx_devices i've extracted and copied xc3028-v27.fw in /lib/firware then i compiled (make/make install) a freshly cloned v4l-dvb Now when the device is plugged there is a kernel oops, I'm missing something or is it a bug? In attachment the relevant part of dmesg, thank you in advance for any help, -- Fab
