Hi folks,

This should fix the issue reported by Qian at [1]. Dietmar mentioned some
other issue with hotplug & deadline tasks, but that's being investigated by
someone else ATM. 


I would like to mention I suspect this bug comes straight from $hell, as
I've never ever had to fight off so many (mostly unrelated) issues while
looking into it. Distro kernel being mangled, git tree corruption, periods of
heisenbugism...

Cheers,
Valentin
