[Xenomai] latency test and mercury

Hi,

I got some really big variations on the latency test (up to 4ms), but
I am not exactly sure if this supposed the realtime portion.
I am unable to run kernel or irq tests.

For a user thread, this is probably like expected since this is a full
debian desktop with RT kernel.

If I understood the mercury model right, I could create kernel modules
with realtime behaviour, Is there any test for latency amongst those?
(Documentation is rather light on mercury)

PS.
I can rule out SMI interaction, the count of those is not increasing.

Kind regards,
Norbert
