How many cores does your current test system have, Ingo? I remember that 
I did not see this on a machine with 24 cores, but did see it on one 
with 36. My initial thought was that it might be related to the fact 
that 24 cores can be described with a traditional 32-bit mask, but I 
wasn't able to find anywhere that a larger mask wouldn't be handled 
correctly.

In my case, it was happening with ixgbe and i40e cards.
