Re: [LAU] options for hard real time kernel for raring 13.04

It may sound obvious, but: did you checked that your are using the
"performance" governor for cpu frequency scaling?

I found that using the "ondemand" governor can cause more xruns...

I don't know mint but there should be a cpufreq-utils package that provides
relevant utilities for this.
