Using O-Profile with Linux RedHat OS => conflict with NMI watchdog


I was trying to run o-profile (a profiling program for linux) and kept getting an error while starting saying something like counter 0 was being use by 'NMI watchdog'. Is NMI part of the OS or is it a separate package that was downloaded? How would I go about uninstalling it?

I tried this on another Linux machine with the same OS and specs and O-Profile ran with no errors.


Solution

  • NMI (Non maskable interrupt) watchdog is a hardware watchdog timer that detects if software has crashed in order to force an automatic hardware reset of the system.
