To confirm you are setting that on both sides on boot?

I am not sure what to make of the instability so far, it is sounding like the
PHY FW you have is buggy which seemed to be a common problem with these
chipsets early on.  There is a report of one version struggling with and then
without EEE in a slightly newer version which both are eventually fixed in the
later PHY FW.  The system I have access to as well as what I've heard from
Netgate seem to be very stable but are running up to date NVMs which doesn't
seem to be ubiquitous on consumer and builder parts.  It may be a hard battle
to get ahold of the right person, but check with the manufacturer to see if
they can provide an update.
