(LPT) Debian 12 Latency spikes/unexpected real time delay. Looking for solution.

The problem with Samba from Windows is that Microsoft put some security in place that by default disable Smaba (SMB) connecting with Linux.
The solution is to edit the SMB policy on your windows box and it works perfectly.

I have no recent experience trying to connect to a windows box, so I really have to rely on the experience of others for that side of things.

Thanks for that.
I believe that what Rodw wrote is the reason why i could not anymore open the shared folder, but its funny that in short time this stopped working, as well as the internet browser and also OneDrive setup on wheezy.

The solution is to edit the SMB policy on your windows box and it works perfectly.

I am not expecting that you write me a tutrorial how to get it work, but if you have a simple tutorial, please send me a link. If the new radeon vga will not solve the latency problem, but i will know that i can setup samba on wheezy, then i will do it. If not, i buy the mesa 7i92TF or 7i76e.

Like Tommylight suggested, try the RTAI kernel, here you can find the newest versions with instruction: forum.linuxcnc.org/9-installing-linuxcnc...ng-rtai-debs-for-2-9

I will do that most likely on today and inform you about the result.

I remember when i installed Debian 12 last year, i had also the rtai version installed, but maybe i had wrong bios settings at that time and went back to this current installed version (i had a picture of my latency test and and top reads this):

x86-64 on host debian 17.Feb2025
Kernel-release=6.3.0-rt11-linuxcnc
Kernel-version=#2 SMP PREEMPT_RT Mon May1 17:18:20 AEST 2023

So, maybe installing the rtai version will solve the latency spikes. Should i do a fresh install or just download and install the rtai version?

Interesting you ran into so much trouble.
I found linuxcnc the easiest Debian version to use. I put it on my daughters MacBook white and it works perfectly for word processing programs etc. Other Linux versions gave me trouble.

I use samba for sending files from my Macbook (osx) to my plasma table. It works perfectly. It is a bit slow but that doesn’t matter. 

Freecad and svg files are small.
