On our product we have recently seen kernel crashes showing the same call chain as above. It happened on two different hosts only 26 minutes apart.
We have a Python program using scapy/sniff. Its effect is to repeatedly put all interfaces into promiscuous mode and then take them out. There are about 10 interfaces, mostly vlan, and it does not create/delete interfaces. This has been running on 7 hosts every 1-3 minutes for days.

I've seen other Google results for crashes in ipv4_dst_destroy that are preceded by "promiscuous mode" notices in the kernel log.
