Re: [Xenomai] rt_task_set_priority hangs/loops sometimes on boot

[Roberto Bielli <roberto.bielli@axelsw.it>]

Hi Gilles,

i attached an image with the stall. (Excuse me for the image but it's 
impossibile in a fast way to convert into text ).
The old backtrace is invalid. The system cannot be updated.
The new backtrace says that the system loop in __ipipe_walk_pipeline.
It seems that irqpend_imask = 2 and irqpend_lowmask = (0, 
4194304,......) are the problem.
In a good start there arent that values.

Can you help me ?

Thanks a lot
