I tried to bisect but the V4L/DVB changes are not bisect friendly, on two 
occursions I just selected "git bisect bad" because the bttv driver wouldn't 
compile, so I couldn't pin-point what causes the oops and hang.

Here are some few observations I made though (I started bisecting between 
2.6.24 and 2.6.25-rc1, saved me ~1000 commits):
1. On the third bisect, there's no oops my PC just hangs a I can't use any 
open terminals
2. When I reached the V4L/DVB changes, my PC did not hag or oops, the radio 
just didn't work (something about invalid VID**AUD**). This made it harder to 
bisect, because it is not working and not breaking so is it good or bad...

Cheers
