The buildbot is now building debs of 2.9:

buildbot.linuxcnc.org/dists/buster/2.9-rtpreempt/

Those still complain about needing Python under 3.10 for some reason, on Linux Mint.

If anyone is having troubles with mesa ethernet cards and  error finishing read, you may like to try (test actually) the 6.1 kernel I built.
drive.google.com/drive/folders/10uwGg5Rv...gODk16na?usp=sharing
You need to install both debs
with
sudo dpkg -i linux-image-6.1.0-rt5-linuxcnc-rt_6.1.0-rt5-linuxcnc-rt-4_amd64.deb 
sudo dpkg -i linux-headers-6.1.0-rt5-linuxcnc-rt_6.1.0-rt5-linuxcnc-rt-4_amd64.deb

Then you need to deterine the driver and the network hardware
sudo apt-get install ethtool 
ip a 
sudo ethtool -i eth0 (where eth0 is the NIC for the mesa card from ip a) 
These should work on Mint as its Debian based.
There are 3 realtek drivers in debian
R8169 (default)
R8168-dkms used by a lot of devices
ref: packages.debian.org/bookworm/r8168-dkms
R8125-dkms
the new 2.5 GB NICs used on the Odroid H3 and others.
ref: packages.debian.org/bookworm/r8125-dkms

So if the device and driver are mismatched.
sudo apt-get install r8169-dkms (for example)

I think the first post could be updated to use these debs for the 6.1 kernel instead as an option if error finishing read is experienced.
kernel: drive.google.com/file/d/1mjv1nKsTdPTDPcL...B0q/view?usp=sharing
headers: drive.google.com/file/d/1BMtApShC1G1vQZK.../view?usp=share_link
They should work on any systems that can install a deb as it is not  a debian specific kernel.
I'vre tested on two PC's without issue. More testing would be appreciated.

I will add this later to the original post, thank you.
I think i have 1 PC with a Realtek NIC, but time is scarce, so no promises.

Nice, thank you.
Those have Intel ethernet, so no issues with those.
Got a used laptop yesterday with a Realtek ethernet, it drops the link at random, despite latency being quite good.

good work tommy .... thanks .... just in these month plan to update from 19.3 because benefit of 5/6 kernel .... but in my opinion 24h of lab test is too few .... need to test 20dd inside tool machine labs for a real test (with all current spike of electrical power in similar area).

It has been 4 days now. I haven't been able to get a failure yet. The new kernel is far more stable. I'm with you, though, I think a few weeks should tell the story.
