So, at least as per the description of John, this should only trigger if
SCHED_HRTICK is enabled in sched_features - which is disabled by default,
it's a debug-only development feature. Does the bug trigger on more
regular kernels as well?
I planned to send it Linus after v3.12-rc1, in the next day or two.
Thanks,
Ingo
