Yep. As I described in the prev email in my case it's a legitimate thing. Some
of the CPU cores are running wireless basestation schedulers and the deadlines
are way too tight for them to sleep (it's "cpu as a dedicated engine" kind of
thing, they are properly isolated and stuff).

In this case actually RT limit is the first thing that I disable :).
I'd rather have stop_machine fail and tell the user that something is wrong.
In which case they can simply stop the basestation app that is running when
convinient. ie It give control back to the user rather than wedging the box or
killing the app.
