Update LinuxCNC 2.9.5 on debian 13 was created by anli
Hi,
I used Debian 12 LinuxCNC image to install LinuxCNC. Afterwards I updated to Debian 13 as shown here in the forum because I needed the newer drivers for display and network because I use an Asus NUC 15 pro. However, I can't upgrade to the new 2.9.5 release using apt:

I ran linuxcnc-install.sh as described in linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel

How can I update to the latest release? Thanks for your help in advance!

Yes, I used that thread to do the upgrade. I reinstalled linuxcnc once again, which seems to have fixed the first issue, but now I run into the next one, please see the attachment.

Looks like the latency is worse than Debian 12 (if Debian 12 was working)

What does:

sudo chrt 99 ping -i .001 -c 60000 -q [card_ip_address]

report ?

Where [card_ip_address] is the ip address of the 7I76E

(the command will run for 1 minute and then print statistics)

One thing I would check is the kernel command line options, did your previous install have any isolated cores ?
Unless the grub config files have not been modified manual editing is required for any extra options.
If the above is not the issue the Debian supplied kernel may require an in depth look at the config.

Or I maybe just barking up the wrong tree and be completely wrong, my apologies if that is the case.

I managed to get it up and running. First I disabled
  • Secure boot
  • Intel SpeedStep
  • PCIe ASPM
  • TurboBoost 
in the bios. Than I could establish a connection and steer the axles. Afterwards I enabled one by one except PCIe ASPM again and I could steer the axles. I ran the above test in this state.
However, some errors remain:

I'll try to fix these - however if anybody has a quick idea what needs to be done to fix them your help is always appreciated :-)
Thank you so far for your quick help to get the machine up and running again!

The SmartSerial is also a latency related issue

Pinning the Ethernet IRQ to the top processor in conjunction with isolcpus=LastCPU
can also help a lot (LastCPU =3 for a 4 core processor)

This script can do this temporarily:
