--- Comment #21 from Michael Meiszl <michael_at_meiszl.de> ---
one more idea where to search:

this machine uses "Intel(R) Ethernet Converged Network Adapter X550-T2" Adaptor
(more ONE, because it is a dual-port card) running on 10Gbe Copper Connection.
After enabling the card it takes really long (>10s) to establish the link with
the switch.
Maybe during this time some "strange" (wrong, cut off or something else)
packets come in and drive the firewall crazy???
Maybe that patch is already good for me even if I do not check for L2 packets

If I get some spare time next week, I will give it a try again and see if the
bug has already vanished. I will report...
