Hi,
i'm having problems loading the bttv-module for my bt878 based DVB-T
card: my system just freezes. 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:

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
