Mesa hm2/hm2_7i96s.0: error finishing read

My /etc/network/interfaces

I wonder if you are being affected by the RTK driver issue rodw mentioned.

Running 5.19.0-2-rt-amd64 #1 SMP PREEMPT_RT Debian 5.19.11-1 (2022-09-24) x86_64 x86_64 x86_64 GNU/Linux.

Using the patch Rodw recommended.
forum.linuxcnc.org/27-driver-boards/4691...ead?start=130#256114

No failure in 24 hours of running.

I gave up on getting the kernel compiled and upgraded to bookworm 6.0. I have a win!
Discussed here
forum.linuxcnc.org/9-installing-linuxcnc...9-13?start=10#256235

I still don't understand why ping times are way high with isolcpus=2,3 but the tmax values are awesome. No finishing read errors after an hour or so. and no real time delays.

Its clearly to do with network drivers.

I didn't have IRQ coalescing disabled because I thought that was only for Intel ethernet controllers.

The cards are always the same old suspects.
What drivers are installed for them?
Which one is the mesa card? sudo lshw -class networkorethtool -i eth0I know I've broken stuff for you before but the Odroid guys say to build the R8125 driver from the realtek source
The other one should be using the r8168-dkms driver
I wonder if we should be black listing existing drivers to get the R8168-dkm driver installed?
 

My Brix was left on all day while I was at work and not one error finishing read showed up!

So I am trying again to compile the 6.1 kernel on i3 but its failing very early in the build. I am starting from the 6.0 kernel non-realtime and preempt_rt both fail,

First I needed to add a few more dependencies Perhaps somebody how has got this working could try building the deb. That would be more useful in the long term. The article says how to install it too [/code]

It would be cool if we could offer a packaged deb. Hosted in Google Drive or something.
