"error finishing read" with Mesa 7i92T on fresh install

Rod: Your detailed document was extremely helpful. It might be worth adding a small blurb about editing /etc/default/grub and running sudo update-grub to get them to stick, or point folks to an existing location where that procedure is documented. I struggled to find a canonical "clean" location of documentation for how to do that. askubuntu.com/questions/19486/how-do-i-a...ernel-boot-parameter was the closest I could find.
 

There is an easier way to do this. The Linuxcnc ISO includes grub-customizer (finally in the debian bookworm repository) which allows you to edit grub settings in a Graphical environment and bypasses the need to update-grub eg.
sudo apt install grub-customizer (if not using the Linuxcnc ISO)
sudo grub-customizer

Using grub-customizer is covered under the heading optional steps. I added some additional detail about EEE and ASPM
Please let me know if it needs changing

That looks good Rod, thank you. I had previously just jumped to the driver section.

For the record, it appears that both updating the driver and setting the kernel parameters are needed. I did a fresh install and just changed the kernel parameters and still encountered the problem.

Once I also updated the ethernet drivers the issue was resolved.

I think that would be right because the 8168 driver is not part ot the default kernel. The dkms driver compiles and installs kernel source. THis is why you need the linux-headers for your kernel. dkms should also recompile the driver if you install a different kernel.

Hey guys,

I'm rebuilding my system after the fires and power surges near LA knocked out my last CNC computer, and I skipped the step on updating the Realtek driver.

I followed the procedure in Rodw's document (thank you again Rodw for all this amazing documentation) but when I'm done, my network to the Mesa card does not come up.

Just to be sure I'm on the right document: docs.google.com/document/d/1jeV_4VKzVmOI..._PhCm1x7oiw8VcLFdiY/

The results of
includes:

My first google attempts haven't solved it, but I'll report back if I do.

But if you guys know what I've done wrong, please shout out. 

BTW: I did discover that if I do what Rodw mentions in the document:

Then I can get the network card back up again. But then it's back to the bad driver too. 

I thought to do:

... but I'm afraid I might never get it working again !
 

PS: I realized that r8169 is not really even a thing, it's just kinda part of the kernel, but just to be sure that wouldn't fix anything, I did try:

but nothing happens: it's an error since that's not a thing that's been installed, unlike the r8168-dkms.

Rod, I'm going to try your 6.3 rt kernel...

note that I think the document docs.google.com/document/d/1jeV_4VKzVmOI...I_PhCm1x7oiw8VcLFdiY

has a typo on line 40... it should be:
sudo dpkg -i linux-headers (tab)
not 
sudo dpkg -i linux-source (tab)

It's really awesome that you put that package up there. 

My 6.3 kernel is quite old now but still ahead of Bookworm's 6.1 kernel
Sometimes I have lost my network with the R8168 and have been able to boot into a different kernel on the system to resolve it. Except I can't remember what I resolved! I think I needed to download something from the internet or run apt

I updated the typo

Aaaand!

You guys are totally awesome!

Installing the 6.3 rt kernel first fixed the network not working after updating to the R8168 driver.

And that driver changed my ping rtt stats obtained from:

from max > 3.0ms to max < 0.2 ms.

Wow.

Hopefully this will improve my error finishing read issues!

Thank you, thank you again!

Yeah, well, I'm considering putting in the effort to compile that 6.6-rt that's over at kernel.org... but then... this might be working, and since pretty soon they'll be out with Debian 13 and then what is it, 6.12? So I dunno.

You were and are a hero to post that super-easy 6.3 install. Thanks again!
