Strangely, I ran xeno-test 5 times and it did'nt hard lock.
I ran bash -x xeno_test and it froze twice at :
+date
ven mar 30 09:44:27 CEST 2007
+ echo running: cat /proc/xenomai/interfaces/rtdm
running cat....
+ eval cat /proc/xenomai/interfaces/rtdm
++ cat /proc/xenomai/interfaces/rtdm
+ wait 2953
Another strange behaviour : I stopped the xeno-test program pressing ctl-C and I
entered commands in the console, and at the moment I heard the PC signal
"beep", the PC froze. (it occurred twice)
I attached gdb to the cyclictest but, the program is supposed to freeze when I
stop it pressing ctl-C
and during debugging that only stops gdb and doesn't stop cyclictest.
So I tried to find where it is blocked using printf() into cyclictest sources.
But when I run cyclictest and I press ctl-C
the PC doesn't freeze anymore but reboot. I restored the original cyclictest
version and ran it, the PC rebooted.
After I reinstalled xenomai (only /usr/xenomai) and when I stop the cyclictest,
the PC reboots

I think it's my last solution. You want me to recompile the whole kernel or
only xenomai ?
