Hi. Full interrupt rate on some CPU means that your system is not idle, but running some process. Another possibility is that you have DUMMYNET compiled into your kernel, which tends to schedule callout for every HZ tick, effectively blocking skipping interrupts for one of CPUs. Check 'top -SH' for running processes, or 'top -SH -m io -o vcsw' for processes doing a lot of context switches. That most likely should give an answer. -- Alexander MotinReceived on Mon Nov 05 2012 - 15:08:08 UTC
