Well, I kind of feel like an idiot now. I had installed Preempt_rt and checked
with ??uname -a?? to verify that I was running preempt_rt.
However, when I rebooted it didn??t boot into the preempt_rt kernel. So when I
rebooted into the preempt_rt kernel linuxcnc would run normally.
I used Synaptic to remove the non-preempt_rt kernels to avoid the future
problem.
Linux alans-optiplex 5.10.0-19-rt-amd64 #1 SMP PREEMPT_RT Debian 5.10.149-2
(2022-10-21) x86_64 GNU/Linux
I am running a 5i25 / 7i76 pair of boards. Should that have the dpll in
it? It doesn??t appear to have it. Is there a new version of the firmware
that I could flash it with.
Alan
In general the PCI/PCIE cards do not have the DPLL included in their
firmware as the host jitter is much lower than the jitter on Ethernet
cards.

I commented out the two offending lines from the new configuration file. Now it
doesn??t error out on the missing lines:
#setp [HMOT](CARD0).dpll.01.timer-us -50
#setp [HMOT](CARD0).stepgen.timer-number 1
However, the very first error is the ??Watchdog has bitten??.
It seems like an error in pncconf if it inserts dpll.01.timer-us where mesa
software has no dpll pins or am I misunderstanding this?
Alan
pncconf doesnt know if the firmware has a DPLL or not
(though all recent EThernet firmware does)
What hardware do you have?
A watchdog bite likely indicates a real time issue with the host or OS.
