hey I am trying to understand why a user space MT process behaves in an unexpected manner. I have real time process, which executes most of its threads in RT priority, and from time to time a task ( medium priority ) is executing without trying to stop. There are times, that this task is hogging the entire process and no other **higher*** rt priority task is getting any cpu time. Linux is **not** getting hogged. when setting the serial console ( irq/serial ) and its shell ( /bin/sh ) to a higher priority linux is responsive. Observing the task list through ps command i can see that this task's threads when to un-interruptible sleep. Any idea why is it happening ? kernel is 3.2.0-rc5-rt8. raz -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
