Advantech PCM 9362 freze when opening latency-test

I think someone may have raised suspicions many many months ago. But my memory isn't what is used........oh ok there's a monkey

That would really require delving into the data sheets regarding the gpios, and how and if the Linuxcnc kernel exposed them, they might be available via sysfs. I have doubts about whether they would be realtime capable.
May libgpiod, but not at all sure.

Use this ISO

Boot the PC from it and run the tests in Live mode, meaning do not install, see if it hangs.
 

 

I tried it its above 35000 and it never froze

Nice, that is still very usable.

RTAI kernels always had issues with hardware, mostly graphic where the resolution would be stuck at 640x480 with no options to change it, there are some examples i posted on this forum when i tested some old PC's.
And i do recall one PC would lock after a while or running LinuxCNC, at random, usually once every two to three days.

i did notice something weird when i install the kernel.
Its says missing firmware module i915
But the display works great.

The missing firmware module can safely be ignored.
The above post can be safely ignored as well.
Tho if it is something you can do and can afford, I would recommend looking at the riocore/LinuxcncRIO project as that can connect via ethernet, is creates step/direction in hardware and as such only requires a servo thread. Another plus being you don't require a RTAI kernel. Just mentioning as this might be worth investigating. The developer is very generous with his time as well and the project is very active.
