panic: mac_lomac_dominate_element: a->mle_type invalid


1. Compile kernel with "options MAC".
2. From the bootloader, "load mac_lomac", "boot"
3. Log in as root, run "ifconfig lnc0 maclabel lomac/equal" (replace lnc0 with
   appropriate network interface name)
4. Trying to log in with SSH causes the panic mentioned above.


Not known.
