Yes, I understand that it's what's happenning and I think that is what shouldn't happen because, IMHO, it doesn't make sense. I think it should be exactly the opposite, as an idle task is scheduled on the same cpu as a higher priority one, it should be run at the frequency of the higher one. -- You are receiving this mail because: You are the assignee for the bug.
