Attached is a quick hack to protect the cached route with a mutex. A
better fix with less overhead would be to allocate the route in a local

enabled. I'll run for a couple weeks with the patch and file a PR if
that fixes it.

I guess this problem was fixed with the following changes:

http://www.jp.freebsd.org/cgi/cvsweb.cgi/src/sys/net/if_gif.c.diff?r1=1.57&r2=1.58
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet6/in6_gif.c.diff?r1=1.23&r2=1.24

Yes, it was. I saw the changes in those files when I attempted to
re-merge my patch after a cvsup. I've currently been running with no
panics for 12 days with rev 1.52.2.4 of if_gif.c and rev 1.22.2.2 of
in6_gif.c.
