The differences between 770 and 770_14 are mainly

o 4kstacks vs 8kstacks and
o newer v4l snapshot in 770_14

Looks like the latter hit you (or are you using cx88-kmdl?).

Edward Rudd already sent me some suggestions to fixing the nvidia
kmdls, but in order to outrule the v4l patches, could you try with
cx88/v4l kmdls in both 770 and 770_14? If you use the kmdls both
kernels should have equivalent v4l functionality, so if the oopses
stop (or come in both kernels), we know it was (is) v4l. 

Thanks!
