Just curious. Do you have this patch from 3.11 applied to your 3.10
kernel tree?

sched: Fix HRTICK
David reported that the HRTICK sched feature was borken; which was
enough
motivation for me to finally fix it ;-)
We should not allow hrtimer code to do softirq wakeups while holding
schedul
er
locks. The hrtimer code only needs this when we accidentally try to
program
an
expired time. We don't much care about those anyway since we have
the regula
r
tick to fall back to.
