I have installed xenomai-2.5.6 on imx53 quick start board with Linux 2.6.35, it works well but stop working when I do some kernel real time task.

When it stop working, system is not totally down, it will be recovered after about 8~9 minutes, which comes regularly. Console operation is as normal if no IO task and without increasing of timer interrupt count(cat /proc/interrupt) before xenomai coming back. I have also tested it with Linux 2.6.38 and xenomai-2.6.0, nothing has changed.

Maybe there are some bugs in my task code, or some misuse of the skin interface. I need help to get some idea:

1 Is there any situation lead to such case(stalled about 8~9 minutes)?

2 Can ipipe trace and proc information give anything useful, which I have to get deeper into implements.
