(注1) dmesg に "bge0:link state changed to UP/DOWN" などが頻発して正常動作しません。
/boot/loader.conf に「hw.pci.enable_msi="0"」という行を追記して一旦再起動することでこれを回避できます。
hw.pci.enable_msi="0"

/boot/loader.conf に以下の追記をするとの記述もあり
--------------------------------------------------------------------- hw.bge.allow_asf="0" ---------------------------------------------------------------------
iLO(HP), BMC(DELL)のネットワーク経由コンソール画面のサポートを無視するのであれば、このオプションで行けるらしい。
em なのに、何故 bge ? と思うが、 hw.em.allow_asf なんてオプションは存在しなさそう・・・
こっちを /boot/loader.conf に記載しろって書込みもある。
--------------------------------------------------------------------- hw.pci.enable_msi=0 hw.pci.enable_msix=0 ---------------------------------------------------------------------
以下でリアルで変更できるので、とりあえず変更して様子見
# sysctl hw.pci.enable_msi=0 # sysctl hw.pci.enable_msix=0

HP G6 の内蔵 NIC
bge0: watchdog timeout -- resetting bge0: link state changed to DOWN bge0: link state changed to UP
/boot/loader.conf に以下を書き込み再起動すると問題は解消します。
/boot/loader.conf
hw.bge.allow_asf="0"

# cat /boot/loader.conf hw.msk.msi_disable="1"
