No.

And something generic as the scheduler time changes ought to 
trigger widely - i've booted up thousands and thousands of 
random kernels with your merge in place - which kind of coverage 
tends to trigger generic lockups and races.

So i'd suspect either an environment dependent bug that random 
testing on a low number of specific systems cannot cover:

 - build environment dependent (compiler?) bug
 - hw environment dependent bug
 - or sw environment dependent bug

... or a mis-bisection.

Thanks,

	Ingo
