Based on this log:

Oct 18 23:08:01 mediapi kernel: [ 7590.369200] em28xx_dvb: disagrees about version of symbol dvb_dmxdev_init
Oct 18 23:08:01 mediapi kernel: [ 7590.369228] em28xx_dvb: Unknown symbol dvb_dmxdev_init (err -22)

it seems you messed the modules install or you have the V4L2 stack
compiled builtin with a different version. 


Thanks,
