Problem seems to be that arp_interval must not be set before mode.

Created attachment 347668 [details] fix I think I found the bug: There is a wrong logic in /lib64/rc/net/bonding.sh: This patch fixes it for me.
There can be either miimon or arp_interval/arp_ip_target but not both. You have to choose only one method so I don't think that this is a bug actually. "ARP monitoring should not be used in conjunction with miimon." /usr/src/linux/Documentation/networking/bonding.txt
Yoou are right about bonding configuration. How about detecting usage of both and show a warning or error?
Your patch is already included in bug e0bbe8d0bde82b14aa9a867707298c2040442151 per bug 447790. As for miimon+arp together, i've added a note in git. *** This bug has been marked as a duplicate of bug 447790 ***
