Hi
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.
Interestingly this only happens after the ubifs root has been updated on the first boot (and not allways). Subsequent boot problems have not been seen.
Any ideas whats causing this? Tim
