OK tested LCNC 2.8 with preempt_rt and the encoder signals make it to
the GUI using a preempt_rt kernel vs RTAI!
NO signal 8 core dump \0/
So it looks like an RTAI bug with 2.8 at least about the encoders
signals to spindle RPM GUI in Axis.
Will go back and trace why preempt_rt has issues with LPT encoders in
LCNC 2.9.
Another odd thing is that when also testing the CH382 LPT PCIe card the
encoders signals are making it from encoder to BOB through the CH382 and
I can see them in halscope BUT the steps generated do not make it out of
the CH382 to the BOB. But CH382 debug is another project.

Bary - Could we get all the files?

I just built RIP on buster and ran the config (remarking out the missing
files)
I have an encoder in pin 10 and 11 and it seems to work with no crash.

Brand new setup using stepconf. if I spin the spindle encoder quickly
by hand I get: rtapi_app: caught signal 8 - dumping core
Even if the machine is still in e-stop. Simple config using stepconf
LINUXCNC - 2.9.0~pre0
All default settings other than manual edit of LPT base address and
changed setp encoder.0.position-scale 4000.000000 Default is like
100 vs 4000
Any ideas what causes this error?
