Here, they are the last latency we get on AT91SAM9261-EK. As just now
I haven't the board at home, I send the last result we stored. The
prority of dbgu should be set to 6 instead of 7, but I can't assure
it, for Xenomai.
first Xenomai:
#insmod /lib/modules/2.6.20.13/kernel/drivers/xenomai/testing/xeno_timerbench.ko
#cd /usr/xenomai/bin/
#./latency -t 2 -p 150 -h -H 500
