Homing no longer working on Debian 10 + LinuxCNC 2.8.0 or 2.8.1

Hi guys,

On my controller PC I've made another partition and installed debian 10 with linuxcnc 2.8.0 initially.
What I have noticed is that randomly, the homing is not working.
Sometimes I can home without any problem, I just power on the machine, homes as it should.
But sometimes, as it happened now, I click Home All, nothing happens, and if I click again, I get a message saying "homing sequence already in progress" but the machine is not moving at all.
Initially I thought its related to my custom vcp made with qtpyvcp, but the same random behavior happens with Axis too.
Its the first time I've encountered this and don't know what to do.
Here is my ini file: github.com/85vmh/SyilX7-MindOverCNC/blob...op/SyilX7/SyilX7.ini
This is using qtpyvcp but, I've switched to Axis and I get the same error message.
Here is a picture of what I see in Axis: photos.app.goo.gl/81Dp4teRjZRokNuB7

Please advice

I have a vistacnc pendant p4s, and sometimes its firmware its not booting.
I don't know if its a coincidence or not, but last time this happened, the pendant failed to boot. Unfortunately, I cannot unplug the pendant easily, because I need to open the controller's box.
I will check next time this happens and see if these two events are linked.
Last days it worked fine.
Eventually, if you could tell me what hal pins, signals to check if this occurs again.

I am using 2.8 for a long time now, even used 2.9 pre, haven't been using 2.7 for a year now. On debian 9, with gmoccapy, I've never had this issue.
I will check if its related somehow to the vistacnc pendant that's not booting up.
Today it worked fine...
