Many thanks for this advice. Indeed, by backporting the pskb_expand_head (and build_skb because it didn't exist) from the version 3.5.7 to 3.4.113 fixes (?) the issue for now. We want to test 3 or 4 machines over night and see if any problem occurs.
Let's see if we can do the same for our 2.6.39.2 kernel (I guess that will be pure pain 😃 ).
Many thanks so far for your support! I will report tomorrow (CEST) if we succeeded.
Mit freundlichen Grüßen / With kind regards
