Hi I have this kernel oops with WinTV NOVA T USB2 As you can see in the log the device is properly initialized. The error happens when trying to actually get and play some video. I use mplayer and after it tries to tune I get the oops in /var/log/messages. I'm using kernel 2.6.16.20 and latest mercurial of today. I can tell that with the mercurial version of 19.06.2006 evening everything works. I've seen some changes in dvb_frontend.c and .h the 21.06.2006, but I don't really understand them. Is there an more debug info I should provide?
