7i92M very weird communication problem!!!

OK here we go:
1. 7i92m with a BOB, and the latest Linuxcnc.
2. card is setup at ip 10.10.10.10 it pings and i can flash the card with the bin file using MesaCT
3. Tested the card with the pathpilot and it works and moved the table.
4. when i use the linuxcnc pncconf wizard or the linuxcnc all comunications with the card stops, even the ping stops responding.
I'm stuck here any ideas?

Not sure about pncconf, but LinuxCNC deliberately blocks card access when running.

Good to know, the only thing is that as soon the linuxcnc is open there is no lights activity at the Ethernet port,

If there was no communication, LinuxCNC should exit.

Are you saying LinuxCNC is running but you have no activity light
(green LED on 7I92 RJ45)?

What does:

ip a

report when in this state?

Linuxcnc is running, the light on the rj45 stays solid green and the lights on the board stay solid without any activity.   

OK, so there is a real time issue that needs to be addressed
before LinuxCNC will run on that system.

To get a rough idea of network latency:

sudo chrt 99 ping -i .001 -q -c 60000 10.10.10.10

This will run for a minute and then print statistics.
