rrsched and i do change when appropriate. As they are used as a cheap
way to get round robin, rrsched is not even initialized. One can argue
that this should be done, but as it literally does not matter where the
value starts counting....

Channels could be dropped and we need to guard against that.

Leftover from various printks for debugging reasons.


Thanks for your feedback,
