PF and MAC framework - panic

I'm a PF newbie only from this week. I've been using IPFilter all along.
On my 6.0 box acting as a router, I was also playing with Mandatory
Access Control, especially mac_lomac. This seemed to work with IPFilter
but the moment I switched to PF, the machine would panic and reboot.
I had mac_lomac_enable="YES" in /boot/loader.conf. This is after I
compiled a kernel with " options MAC".
in /etc/sysctl.conf I had the following:
And in /etc/rc.conf, all active interfaces were configured with
"maclabel lomac/equal" added to the ifconfig args.
I'd switch from ipfilter/ipnat to PF by flushing rules in this order:
pfctl -f /etc/pf.conf
At this juncture, the box would panic:
panic: mac_lomac_dominate_element: a->mle_type invalid.
A memory dump would then occur and the box reboots.
I went a step ahead: disabled IPFilter in rc.conf and enabled
PF and rebooted. The box would fail to reboot in this case and
panic over and over until I disabled mac_lomac_enable="YES" in
/boot/loader.conf, the relevant entries in rc.conf and sysctl.conf
Anyone using MAC who can reproduce the same?
