Can't get Mesa 7i92 to connect without a hub.

I didn't know about that IRQ issue.
Ran the following Didn't help anything. (did change ethN to enp2s0)

sudo ethtool -C ethN rx-usecs 0

I saw there were commits on May 10 to correct and add some things with the 7i92 in pncconf including the correct driver. But, can't seem to get that compiled in or running with the changes. Wanted to start with a fresh HAL and INI with the right boards rather than edit things. Anyways, here are my very basic files that I'm trying to make sure the may hardware works before going to crazy adding things.

So the basic hal structure looks OK

Maybe some network setup issue?
what does

ip a

print?

Also can you start linuxcnc from a terminal and copy/paste the exact terminal log here? you log looks very strange relative to what I get

You can start linuxcnc in a terminal without launching the chooser by typing
linuxcnc yourinifilename
from the config directory

Here you go...

So that's pretty mysterious. Did you disable ipv6 as suggested in the hm2_eth man page?

Other than that I guess as I mentioned before, it could be marginal interface levels on the 7I92 so it works with the hub but not reliably with a direct connection, or may be something else odd about your setup.

Are you using the stretch test ISO?

Yes using Stretch test ISO installed.

Discovered this... Given the little black box J1900 is gigabit connection and 7i92 is 100... the hub handles the conversion. When directly connected it fails.

BUT, when I force the J1900 to use 100MB it also fails with the hub to the 7i92

Note: Network, INTERNET and other items work fine when forced to 100MB. Very frustrating stuff. May try another firmware see if any improvement.

I don't see a reference to disabling IPv6 in the MAN pages. But have attempted to on your direction.

For an experiment installed the 7i77x2D firmware ... but same results. Going to be out of town... I guess I will have to try another PC after next week. To see if something with the J1900, Ethernet ports, OS or the 7i92 itself.
