Anyway after nearly ten years, due a lack in resources, i'm sadly going to suspend the CRUX PPC project and my activism pro free software thus i'm unable to follow these debug. I'll hold on to me the only YDL Powerstation then from the next weeks i'll can only follow trying to help in debug [1] on this specific machine.
