>Description:
When using MAC with lomac security policy and MAC_DEBUG
mac_lomac_load=YES
security.mac.lomac.trust_all_interfaces=1

system panics some time after connecting to internet via user level ppp and
modem. This do not happens every time, but quite offten. I can reproduce it
without major problems. I have never observed this thing in normal (not using
modem connection to internet) use. 

Panic message is:
mac_lomac_dominate_event a->mle_type invalid

Crash dump was never successfully created. System hangs while trying
to do that.
