Disabling IPV6 Results In Core Dump

This may be a known issue, but I am submitting in case someone else is stumped (as I was).

If ipv6.disable=1 is included in the linux kernel command line the following error occurs along with a core dump.

If ipv6.disable=1 is removed, the error no longer occurs.
