I upgraded to 4.8.7 and the system boots and my root partition gets
decrypted but right after that both of my monitors turn off and
looking at syslog from 4.8.6 shows the following:

Hmm, there's cleanup_net() namespaces fun in there, adding netdev@.

Probably this warning in source code:
void retire_sysctl_set(struct ctl_table_set *set)
{
WARN_ON(!RB_EMPTY_ROOT(&set->dir.root));
}

Looks like net->sysctls is not empty when unregistering,
perhaps unregister_net_sysctl_table() is missing somewhere.
