More - Error Finishing Read

Hi All,
I'm getting an Error Finishing Read after a couple hours of run time on a Dell OptiPlex 9020.
I followed Rod's Google doc (Nice job!). I've also rattled the ethernet cable while running and routed it away from some noise sources.
It is not shielded cable. I believe it's an Intel NIC. 

 I've included some images which show values from questions in other threads. 

Any suggestions?

Thanks,
Steve
 

First, to make sure of your hardware, you can run

lshw -class network

 

Command not found.

dmesg | grep -i eth

or perhaps

sudo dmesg | grep -i eth

should also work

or install lshw

steve@debian:~$ sudo lshw -class network

OK it looks like you have the Realtek Ethernet setup for the 7I76E

Is that what you had intended?

If so, you need to

1. Install the Realtek 8168 DKMS driver
2. Disable Ethernet and ASPM PCIE power management in the kernel command line

Hmm, it looks like I got them backwards. I’m away until tomorrow afternoon but I’ll have a look then.

As always, thanks for your help!

I added the 8168 DKMS driver, added r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off loglevel=3 to kernel settings and removed the no longer appropriate "hardware-irq-coalesce-rx-usecs 0" from interfaces.

I ran it a bunch yesterday and never saw the error so I have high hopes this was the problem.

Thanks once again for your help Pete!

Its amazing the difference when the right driver is installed. The 8168 driver really should be part of the default kernel. I've been cofiguring a PC with the R8111 with a Mesa card for the last couple of weeks. The only EFR I've seen is when I power off the Mesa card with Linuxcnc still running.

This computer was the reason why I went looking for solutions a couple of years ago and since then  many others have chipped in with enhancements.
