Issue
How can I improve event response times (latency) for my realtime kernel on IBM BladeCenter systems?
Resolution
The ibm-prtm package available with Red Hat Enterprise Linux MRG contains a utility and startup script for certain IBM BladeCenter systems. It enables an Error Detection and Correction (EDAC) driver and turns off generation of System Management Interrupts (SMI), which improves system response time to events.
