Hello all

Im new to this mailing list :)

Im using a gentoo amd64 kernel-2.6.13 system with a Hauppauge DVB-s Nova 
CI. The driver is working (im using vlc) but I get strange messages in 

dvb_ca adapter 0: DVB CAM detected and initialised successfully

This looks very bad to me! the /dev/dvb/adapter0/ca0 is locked now, even if I terminate vlc.
It's even unpossible to rmmod the budget-ci module.

any hints?
