[Nut-upsuser] mge-shut driver fails almost after every reboot

[Panagiotis Kritikakos]

Hello Arno,

Thanks for the quick reply. FreeNAS is FreeBSD-based.

Yes, I could test a patch.

As I have mentioned, this behavior is not seen at every single reboot 
but after most reboots. Also, some times, the connectivity can be lost 
without even rebooting. That is not very often can have happened a few 
times.

Best regards,
Panagiotis
