Hi, [ weird, Gmail thought you were a spamer... ] Sergei Shtylyov wrote: No, it doesn't. Even on dyntick kernels, interrupts do happen several times a second. Dynticks have nothing to do with disabling timer interrupts...
That's true however if your system has 2 clock devices. One is the r4k-hpt
and the other one soemthing else with a higher rating. If you don't stop
r4k-hpt interrupts, how does it work ?
