Hi All, Tried to update my v4l-dvb modules today, but got a bug with my pinnacle card, seems to be related to the recent changes in the ir code. I have added dmesg output of the bug (changeset a871d61b614f tip), and dmesg output of the previous modules (working). -- Sander Dec 5 23:30:25 security kernel: [ 5.596128] em28xx: New device Pinnacle
