Hi Jan
If I activate ftrace, the kernel is crashing while the system is
booting. I can not see at the moment where the problem is.
Is a ipipe trace also a option for you to get more informations ?
If yes a can trace a good and a bad working cycle.

Hi
The linux tasks are not blocked (not all).
I think the problem is , that the linux scheduler function in the kernel
is not called for some ms.
I have also traced the calls to the scheduler function
"static int __sched __schedule(void)"
and sometimes when the decribed problem occur this function is not
called while no linux task are running.
If no task is runnable, there is also no reason to invoke schedule.
Please post a ftrace log of your system, covering both a working and a
non-working cycle, including cobalt* and at least sched and irq events.
