Subject: [Xenomai] Context switching kernel tracing

Hi,
I have got some problems with an architecture, and 2 realtime tasks.
The realtime is not always respected.
This is a very strange problem in this architecture, since it happens
statically almost every three reboots...
It looks like there is something in the kernel / or setted up by bios
that is happening and locks the task switching context.
I implemented LTTNG 2.0 tracing in my target, I would need to know which
xenomai functions/events are interesting to watch in my kernel traces ?
Regards,
S.Ancelot
