Unexpected realtime delay on task 0 with period 1000000

I'll see what I can find, I'll take photos of the bios, I don't know anything about it

You should run the latency test without a base thread:
latency-histogram --nobase --sbinsize 1000

YOU mean stuff in the bios?I would guess you still have some power management ( EIST, cstates > C1 , Turbo mode etc ) enabled

If I set it up like this, I will no longer have a network
or what did you mean?
Code:
CPU Configuration
Hyper-Threading [Disable]
Active Processor Cores [All]
Intel Virtualization Technology [Disable]
VT-d [Disable]
Enhanced SpeedStep [Disable]
Turbo Mode [Disable]
Package C State limit [C0]
or what did you mean?

If I leave it like this, I have the search symbol in the top right-hand corner of Linux and no Internet connection
LinuxCNC starts, the network symbol is there.
A short time later, Linux CNC hangs up and I have the network search icon in the top right corner of Linux again.
I can't get the Internet to work with these settings and LinuxCNC crashes (frozen screen and no longer responds)

$ sudo nano /etc/default/grub
Change line: GRUB_CMDLINE_LINUX_DEFAULT="quiet"
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet, isolcpus=2,3"
$ sudo update-grub
Also, what sort of latency and packet losses (if any) do you get when you ping the interface?
$ ping 10.0.0.10
and
$ sudo ping -f 10.0.0.10

The new dug
$ ping 10.0.0.10
How can I stop this?
$ sudo ping -f 10.0.0.10
I can't get this cancelled
$ ping 192.168.1.121
$sudo ping -f 192.168.1.121
it remains one .
