New and Lost

I am new to linuxcnc and linux in general. I am trying to set up a 7i76e with a 7i84 to run a lathe. I am unable to get configuration to work. I have attached my results, and would appreciate a push in the right direction.
Using Linux mint operating system

LinuxCNC terminated with an error. You can find more information in the log:
/home/emc/linuxcnc_debug.txt
and
/home/emc/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal
emc@cnc ~ $

A couple of things:

1. Your ping test is not pinging the 7I76E (just a local loop back)
( also its often better to use the 10.10.10.10 address option of the 7I76E to avoid overlapping
non- real time network connection IP address ranges)
2. Are you running Preempt-RT? that is did you install a real time kernel in Mint?
3. Did you run a latency test?
I would suggest running this test a hour or so while running other normal things on the PC:
latency-histogram --nobase --servo 1000000

you appear to be running POSIX and not rt-preempt
