To get more information about scheduler work, use > /usr/src/tools/sched/schedgraph.py (instruction inside it). I rebuild my kernel with KTR. But I'm not a dev so I have no idea what the schedgraph.py show...:-( If this can help to solve the problem you can find my ktr and my dmesg. http://dl.free.fr/csycL43ad http://dl.free.fr/j0XQFimPM Hope that can help you. If you need anything else .... Thanks. Regards.
