>Description:
	8.2-PRERELEASE with stock em(4) driver version 7.1.8 panices
	under moderate network load in the driver.

	The system is PPPoE network access server using mpd-5.5 and NETGRAPH.
	User sessions are created/deleted quite quickly.
	The system has only two up and running interfaces corresponding
	physical NICs: em0 is uplink having IP address,
	em1 has not IP address but has many vlans on it carrying PPPoE frames.
	vlans do not have IP addresses too. Both interfaces are configured in /etc/rc.conf as such:

ifconfig_em0="inet $myip netmask 255.255.255.248 -wol"                                                                         
ifconfig_em1="-wol"

	I've got full crashdump for total 4GB of router memory.
	Here comes gdb backtrace. Then dmesg output, kernel config file,
	loader.conf and sysctl.conf.

	this particular box has no lagg devices configured.

>How-To-Repeat:
	It takes several days for panic to occur
	and seem to depend from load: more load, less time to panic.
	This particular panic occured at 4th day of uptime.

>Fix:

	Unknown.
