Do you mean idle tasks = task_b in above context? Why task_b slows down the normal priority task is because that, the cpufreq decrease due to task_b's high nice value, and task_a is scheduled on the same cpu. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
