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
