Hi Matthias, I've seen the same effect (PHY reset) quite rare, but they have been there. As it's horrible losing a device this way, I'm doing a periodic poll of some few important PHY configuration registers and compare them with the values they should have. When I detect a change here (due to a PHY reset), I'll reconfigure the PHY "on the fly" which fixes the problem.
As I'm also writing this event to my event logger I see when this happens ... have not seen it for months in a 24/7 operation, but I feel better to know that I'm not losing devices in the network if this happens.

I'm pinging the device while operation now and when I loose connection I see that I receive no ping response and a few seconds later the host is unreachable. Is there a way to detect a reset of the PHY and reset it again?
