Magic-Syskeys also won't work then. With kernel 3.9.0 this worked just fine. Versions 3.10, 3.11 and 3.12 won't work. Last messages on screen with 3.12 upon booting/loading the module is: http://abload.de/img/bttv_freezeqxdn2.png With kernel 3.9 i get an additional line on module loading and the device works fine: [ 1.895037] bttv: 0: add subdevice "dvb0" I traced the problem, it dies somewhere in v4l2_ctrl_handler_setup on line 4169 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/media/pci/bt8xx/bttv-driver.c#n4169 lspci output from kernel 3.9: [...] 04:01.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) Subsystem: Twinhan Technology Co.
