Hi

I have further input to the ksoftirq/0 using as much cpu as available on a
arm i.mx pcm043 platform without load with a 3.0.14-rt31 kernel and some local 
platform adaptions.

I was thinking about this ksoftirq0 running on max cpu. The context:

and the running wild ksoftirqd0 most probably after the kernel
message: "sched: RT throttling activated"

I think that the message  "sched: RT throttling activated" and the ksoftirqd 
running on full cpu are possibly to seperate errors. Btw. is there a way to 
find out which processes where conuming this timeframe. It would be nice to add 
info output which processes caused the throtteling. Is it possible to get this 
information out of the scheduler structure?

Peter,

This is your territory.
