Herbert, in https://bugs.FreeBSD.org/201642 I had tracked down the 
commit that caused the issue on our Soekris 6501s.  Only between r284297 
-> r285662 in HEAD and between r284998 -> r285756 in stable/10 should be 
affected.

 >>>Ok, it is 10.2-BETA so I've tried 10.1-Release next...exactly the same,
 >>>ok tried 9.3-RELEASE .. the same!

Holm, if you are seeing this on 9.3-RELEASE and 10.1-RELEASE I'm not 
entirely convinced the cause is the same.
