Hi This is just a followup > We are having a problem with a slightly patched (some platform patches, > newest stable ubifs patches) 3.0.7-rt20 kernel after updating the firmware > on the first boot we get a message: > sched: RT throttling activated > and ksoftirqd/0 taking 95% of the cpu time. RT throtteling is still activate with 3.0.9-rt25 (+ ubifs stable patches) but now ksoftirqd/0 is not going berserk. > Interestingly this only happens after the ubifs root has been updated on > the first boot (and not allways).

Ok the only nitpik that is left, that the processor activates rt throtteling after the first boot with updated ubifs image. > Any ideas whats causing this? Well it can be said that it is not ksoftirqd/0 going berserk which is triggering this. So i guess when this message is printed it just shows that the cpu had been temporarily overloded with work in interrupt context. Is there more harm to expect from this message or save to ignore if the systemload is normal again?
