Ok, I just wanted to see the current load all the time :-) Btw. I don't think that just one top running should cause alsaplayer (which runs with real-time properties:
-r, --realtime Enable realtime scheduling. To use this as a nor mal user, alsaplayer must be SUID root.
As I wrote in a seperate mail alsaplayer skips during other activities also, like starting mutt, mozilla, whatever ... And these are not started reniced.
Since I am not using md there are not that much changes left between -pre10 and -pre11. Or do you think that it is caused by the console locking changes?
