Hi all,

when I try to unload xeno_nucleus module I get a kernel panic and on the
next power on the bios system date is reset.
when configure xenomai nucleus built into the kernel I can reboot correctly.

Kernel panic log would help.

I'll try to get it

In the bios I disabled HPET and most of the things r=
egarding PM and ACPI.

Here attached same info about system and kernel config.

If possible, I prefer have xenomai configured as modules, is there
anything wrong about my system configuration ?

This should not be a configuration issue. Either some kernel-based=20
Xenomai threads (e.g. RTDM driver thread) are still running when=20
attempting to unload the nucleus, or a real-time IRQ is still hooked to=20
a handler being unmapped, or there is a nucleus bug.

after boot the only thing I do is load nucleus and unload it, no other xenomai modules are loaded

Thanks
Alessio
