Hi ALL !
I have several servers with FreeBSD 8.0-PRERELEASE on SuperMicro with 
different Intel NICs. When I create new vlan on em interface
( ifconfig vlan557 create vlandev em0 vlan 557),
it hangs down and then up and server becomes inaccessible by ssh, but 
reply on icmp request.

on amd64, custom kernel:

em0@pci0:13:0:0:        class=0x020000 card=0x108c15d9 chip=0x108c8086 
rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel Corporation 82573E Gigabit Ethernet Controller 
(Copper) (82573E)'
    class      = network
    subclass   = ethernet
em1@pci0:14:0:0:        class=0x020000 card=0x109a15d9 chip=0x109a8086 
rev=0x00 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel PRO/1000 PL Network Adaptor (82573L)'
    class      = network
