Does this kernel have the real-time patches applied? It doesn't look
like it from the name.

Let's make sure it's configured. MAke sure /usr/src/linux points at
your kernel and then run

cat /usr/src/linux/.config | grep CONFIG_PREEMPT_RT

mark at lightning ~ $ cat /usr/src/linux/.config | grep CONFIG_PREEMPT_RT
CONFIG_PREEMPT_RT=y
mark at lightning ~ $

cat /proc/sys/kernel/sched_rt_period_us
cat /proc/sys/kernel/sched_rt_runtime_us

Thanks,
Mark
