Hey there,
I get this error in dmesg on my 6891:
[ 21.517047] cx25840 2-0044: firmware v4l-cx23885-avcore-01.fw load failed
[ 21.524868] cx23885_dvb_register() allocating 1 frontend(s)
[ 21.524874] cx23885[0]: cx23885 based dvb card
[ 21.525933] tbs6981fe: module license 'TurboSight Proprietary: www.tbsdtv.com' taints kernel.
etc....
The card works ok, but I would like to know if this is something that I should be worried about. I've tried switching the firmware with the one that comes with the TBS driver bundle which gives the same results.
My system is running Ubuntu 12.04.2 on kernel 3.5.0-26-generic with driver version 130318.
Thanks,
Ali.
