Kaby Lake isn't exactly old.

That's i386 limits, the other memory is mapped outside of the 32bit
address space. You either need the PAE kernel or go to 64bit.

What happens with SMP and ACPI ?

I219v2 Controller. That would be the wm driver, but it doesn't support I219 yet.

I'm using a couple of simple wm based cards. Last one was "Intel Gigabit
CT Desktop Adapter", e.g. https://www.amazon.de/dp/B001CY0P7G.

Not using ACPI might have some "interesting" effects. Check
vmstat -i and vmstat -e for rapdily occuring interrupts or events.
