I did try to track it and I may still have logfiles with a lot of debugging messages. Should I try to find them ?
IIRC it happens more or less just before I get the first prompt on the serial console. But later the counts match again, so it's a very temporary condition. What I don't understand yet is how something looking like a race condition can be so reproducible.
