>Description:
On SuperMicro servers with FreeBSD 8.0-STABLE amd64,i386 with
different Intel NICs(82573,82546), when I create new vlan on em interface
( ifconfig vlan557 create vlandev em1 vlan 557),
it hangs down and then up with GENERIC kernel and server becomes inaccessible by ssh, but reply on icmp request with custom kernel.
