Subject: How to disable Lazy Preempt in the kernel

I'm relatively new to Linux and working on getting a real-time kernel up and
running for robot applications. I'm on Ubuntu 14.04, using kernel 3.14.3 and
the 3.14.3-rt5 real-time patch. Also using x86-64.

There's a known error where the whole system crashes under some load when
lazy preempt is enabled. This has happened to me a few times now. My
question is:

How do I disable lazy preempt?

Thanks for the help!

-Tom
