Hello Arno,<br>
<br>
Thanks for the quick reply. FreeNAS is FreeBSD-based.<br>
<br>
Yes, I could test a patch.<br>
<br>
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.<br>
<br>
Best regards,<br>
Panagiotis<br>

Problem description:<br>
<br>
This was originally reported as bug to FreeNAS (<a
moz-do-not-send="true"
href="https://bugs.freenas.org/issues/8049#change-41087"
target="_blank">https://bugs.freenas.org/issues/8049#change-41087</a>)
and was asked to post this upstream, so here it goes.<br>
<br>
The issue with the driver has been seen in FreeNAS
9.3-STABLE. While the serial connection with the UPS
(Eaton 5 5SC Serial with mge-shut driver) is working
initially, almost after every reboot, the driver is
failing with the message "UPS failed - Driver not
connected". This was not the case with FreeNAS 9.2 and
NUT 2.7.1.<br>
