Mesa hm2/hm2_7i96s.0: error finishing read

Rod - yes, the 'backup' PC has an 8168.  The earlier failures were on an HP elitedesk 800 G2 I bought because the other one was unusable because of the realtek NIC.

I've got non-free in the sources, and dkms vomited while trying to install it.
 

DKMS needs linux-headers. Did you instll them? Using $(uname -r) makes sure you get the right one for your running kernel

Yep, shows up in synaptics.

not seeing a Real time version
Do you have a PREEMPT_RT kernel installed?
What does uname -v say?

6.5.0-0.deb12.1-rt-amd64

I burned the trixie iso, updated, then used synaptics to install linuxcnc.  Then downloaded the rt kernel Tommy linked to earlier from the Debian site.

I've obviously done something wrong again.

EDIT - it's getting late, need to get some sleep now.  Maybe I should try the standard LCNC iso tomorrow and see how it behaves on this PC.

Ok, back in the saddle.
Quick try with MX23 both with 6.1 and 6.5 rt kernels.  No joy, still getting read finishing errors.

What's the next disto/version/kernel/NIC driver combo to try?
