Mesa hm2/hm2_7i96s.0: error finishing read

How do I make this stay? It reverts after reboot.

Thtas covered in the docs  here:
linuxcnc.org/docs/devel/html/man/man9/hm...FACE%20CONFIGURATION

I'm not sure if anybody can hep but I compiled the 6.1 kernel per Peter's instructions but at the end of the
sudo make INSTALL_MOD_STRIP=1 modules_install 
command, I got 

I got this error and make install did not work.
Also as an aside, after several upgrades this PC starting with the Bullsye 5.10 kernel got this kernel
Any ideas about this?
From what I can gather I can now add preempt=full to grub  but I don't know if this will give me the fully preemptible kernel. I'll see what happens
It would be coolif we could set PREEMPT_RT from a grub setting. So here goes...

Well, that got me nowhere!
Reverted to the PREEMPT_RT debian deb for the 6.0 kernel
Now I've lost my ethernet card to the Mesa 7i76e grrr...

so tried this:
time to reboot because I saw it compile the driver we need.

I would try 6.1 and 4.19

6.1:

sudo apt-get update
sudo apt-get install build-essential bin86 kernel-package libqt4-dev #libncurses5-dev pkg-config libssl-dev

mkdir rtlinux
cd rtlinux
wget git.kernel.org/torvalds/t/linux-6.1-rc3.tar.gz
wget www.kernel.org/pub/linux/kernel/projects...6.1-rc3-rt2.patch.gz

cp patch-6.1-rc3-rt2.patch linux-6.1-rc3
cd linux-6.1-rc3
cat patch-6.1-rc3-rt2.patch | patch -p1
make xconfig
make -j4
sudo make INSTALL_MOD_STRIP=1 modules_install
sudo make install

4.19
cd ~
sudo apt-get update
sudo apt-get install build-essential bin86 kernel-package libqt4-dev #libncurses5-dev pkg-config libssl-dev

cd linux-4.19.255
cat patch-4.19.255-rt113.patch | patch -p1
make xconfig
make -j4
sudo make modules_install
sudo make install


Both work acceptably on my somewhat troublesome Elite 800 G1
 

I get the following error when I try and install the packages.

I just tried 6.1 and got hm2/hm2_7i96s.0: error finishing read! iter=73208
I used the following corrected code to build and install.

What are your ping times with 6.1 and do you have IRQ coalescig disabled?

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

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