"Watchdog has bit" usually means really bad latency (>5 ms)
Running
halcmd show param *.tmax
in a terminal when LinuxCNC is running
will give more information
What is the host hardware and clock speed?
Also do you have all power management/turbo modes/speedstep
etc disable in the BIOS? Really bad latency is quite often related
to CPU power management.

You need to disable turbo boost, C states > C1 and speed-step

I am still getting the same error even after disabling these. Is there anything that can be done further maybe give the computer more margin for error if thats possible?

open a terminal and type
sensors
see what temperature the CPU is at while LinuxCNC is running, anything above 60 degree C should be mitigated by re-pasting the cooler or replacing the fan or with better cooling.
Some processors will handle over 90 degree, some Intel Xeons will throttle badly at 63 degree only!

Other things to check:
1. Do you have an Intel or Realtek Ethernet chip?
( there are chip specific things you can do to improve latency)
lshw -class network
Will list your Ethernet (and wireless) network hardware if you are not sure
2. Have you run a simple ping test like:
ping -i .2 -c 4 10.10.10.10
sudo chrt 99 ping -i .001 -q 10.10.10.10
(use 192.168.1.121 instead of 10.10.10.10 if your 7I76E is set for that IP address)
The first command populates the ARP cache so the ARP lookup doesn't add time to the first ping
The second command should be run for a few minutes (and then stopped with a control C)
and the results posted here.

DAMN!!!!
That is 99 degree C all cores all the time, no wonder the PC is giving up it's ghosts, slowly and painfully!
The good thing is, you have it easy to remove the CPU cooler and clean both the CPU and cooler, then find some thermal paste and apply some to the CPU and mount the cooler back.
Tooth paste works instead of thermal paste, albeit for a day or two only.
