recent Update makes LinuxCNC defect

I want to switch from normal HD to ssd. There is no other change in Hardware, neither the PC nor the CNC machinery.
It works over parallel port and M542 driver as for years. The mill itself is a DIY 3 axis machine.

I downloaded the current Debian Amd64 2.9.3 PREEMPT-RT Hybrid ISO and installed it.
Also I did create a new config for Gmoccapy/machine, my current config is just to old to get converted (got a lot of errors). Anyway, the installation went OK and the machine is working as expected.

Now I did an upgrade
which in general also went OK. Paranoid reboot and start LinuxCNC. Now I got the issue all but Y-axis moving. The motor gives some noise but not really moving. Whatever I tried, changing/relaxing timings and so on, it did not start to work correctly. X- and Z- still working.

I did search but did not found similar issue messages.
The question is, may someone had an easy fix or should I just reinstall and avoid upgrade for some time?

Thanks for reading,

Please supply config files.

Good news.
I got it working in changing the control pins for Y-axis (from 3/16 original Y-axis, to 5/6 original A-axis) on the parallel port.
But it is really weird why 2.9.3 is not working in the original Y-axis config but the old config still works with this config.

Attached the original config. As said I just swapped 2 pins around...
btw. the old version I was running was 2.7.0 Pre, I did build them myself from sources.

Thanks a lot,

Hmmm that's a weird one.

At a guess it could be a local hardware issue that manifested itself when you made the changes. As this is a guess I could be wrong.

Many many moons ago I had a PSU fail when I did an upgrade from Win2k to WinXP. I think the gremlins that lived in the PSU thought it would be funny to push the fail button just after I did the upgrade. They seem to like Linux more.
