So, the i2c handling of b2c2-flexcop needs to either be fixed or hacked to prevent this problem... I think we have the same problem in 2.6.21.y -- I couldn't get it to work at all, there. 2.6.20 works fine. (we absorbed lgh06xf.ko into dvb-pll as of 2.6.21 -- that explains it) Cheers, Mike _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
