Can you please post the chrony configuration? Are the SOCK and PPS
refclocks using the same (GPS?) device? Normally you would have only
one, or the other one marked as noselect if it was using for locking
of the first one.

with IO board) both were running fine over longer period but now it was 
time to upgrade OS (to Deb Bookworm) and now one of them is running like 
normal but the other one:
