Hi,
I use an Intel dual nic for my home server. About two weeks ago, it
started to randomly stop
working. A reboot solved this problem. Today it did not even work
after a reboot.
Since the cooling of my server was insufficient for this summers heat,
it might be a hardware
issue.
I already checked the cable, that seems to be fine. I also ran the
Intel diagnostics (on windows)
on the cable and on the card, which showed that everything is ok.
Any idea what the reason might be is appreciated :)
See debug infos below. What is especially strange is
dev.em.1.debug: -1. I cannot change this, it will stay at -1. Also,
the error count numbers from
sysctl are mostly the same, which is very strange.
