I am still running 5.3-RELEASE-p5 and there is
/*$FreeBSD: src/sys/dev/em/if_em.c,v 188.8.131.52 2004/10/15 22:12:59

, obviously unpatched and bad driver. I'll try to cvsup to 5.4-PRE, but
I'm a little worried with stability, as this is my main firewall for
2nd thing... try to disable it manually ? What :) ? I don't quite
understand you on that .
ifconfig em1 disable ? :) I have traffic on it :) ( I'll be running
carp as soon and pfsync as I'll learn how to and if it will work fine
:) , to have redaudant firewall )
