I've snipped the log output - it was such a wordwrapped mess :(
Can you please resend it in a reply-to-all to this email, after ensuring
that it won't be wordwrapped?
Thanks.

There is two crashes.

Changing from FIB_TRIE to FIB_HASH, and it is not panicing anymore. It seems
recent patches to FIB_TRIE broke something (i have complicated setup with ifb,
maybe it will help). If you can point me to any patch, i can reverse it and
try again with TRIE.

Unfortunately there were 39 changes made to fib_trie
during this time. So it's not like we can give you
one patch to try reverting :-/
Really, the fastest way to track this down would be
to do a bisect, focused in on net/ipv4/fib_trie.c
which git bisect does allow you to do.
