Scientific Linux > Kernel > rtcheck: failed on booting

Posted by: insomnia May 26 2016, 12:51 PM

i am running Scientific Linux 5.x and i have installed the real time kernel provided from MRG packages.

While booting, on initialization i can see the message:

Starting rtcheck: Checking if system is Real Time capable: [OK]

However, when typing in terminal the command:
rtcheck -v

It gives me:

RTCheck 0.7.6 - Linux Real - Time Environment Checker
RTCheck Initialization:
  Locking all memory:   ok
  Setting up real-time scheduling:   ok

Is everything working properly?
