Erros: Unexpected realtime delay + 7i96s error finishing read

Hi folks,

I´ve recently installed Linuxcnc 2.9.3 to run a BF20 milling machine equipped with a Mesa 7i96s.

PC-Mesa card communication is ok, tested both with ping and mesaflash tool.

I have configured the parameters in PCConf wizard with the appropriate IP (10.10.10.10), but when I start Linuxcnc I get these two errors....I am completely stuck:

Hello,
you need to sort out latency issues.
How is your latency-histogram looking?

There are also Ethernet interface specific adjustments needed on some systems

Whats does

lspci | grep -i eth

report?

Hi guys!!! Thamk you Tommylight, Zmrdko and PCW

I managed to solve the latency error by isolating one cpu of the processor. Now it doesn´t trigger the message, but there´s a new visitor....

Now the annoying "Error finishing read" appears too often, sometimes even while running the small "Linuxcnc" test program G-code.
The computer is a basic Lenovo tiny M600 with an Intel Celeron (2 cores). The ping values doesn´t seem to me to show crazy high msec values.

One more time, I´m completely lost in the journey!

The m600 uses a Realtek MAC so likely needs the DKMS driver
(the built in Linux one is defective and has random 10 ms or greater hangs)

Take a look at this thread:
