Kernel crash when you wish to change interface name from vlan0 to other name

It seems to be in arrival/departure events.

1) when I set up vlan0 and change name to mgmt and after that destroy mgmt.
 kernel crash in bpfdetach() at line 2495. where it tries to find interface structure.
2) when I setup vlan0, change name to mgmt and set ip address. After few seconds 
 kernel crash in vlan_transmit() at line 1029. where it tries to push mbufs to bpf interface, but it is NULL.
