Subject: How to disable Lazy Preempt in the kernel
Date: Thu, 19 Jun 2014 08:11:21 -0700 (PDT) [thread overview]
Message-ID: <1403190681610-885003.post@n7.nabble.com> (raw)
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
