I've found this:

which seems to be the place where the kernel dies according to the bt. I 
hope qingli will take care of it.

And for the bge stuff, I've just noticed that allow_asf is off in 
7-STABLE, so it's probably not a regression in code, but in behaviour. 
(which can be more easily fixed, but I don't know whether it worths to 
be on)
