When I did my testing of tuner-simple and tda8290 modules, I ran into some OOPS as a result of some simple issue, easily resolved. As I hit those issues, I was able to take care that the problem would be prevented in all new modules... If you get an OOPS in your testing of tea5767, just send me the dmesg output -- I'll probably be able to fix it immediately, although I doubt there will be any problem. Thanks in advance for the testing. Cheers, Mike _______________________________________________linux-dvb mailing listlinux-dvb@xxxxxxxxxxxxxxx://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
