em0: Watchdog timeout -resetting

[Miroslav Lachman]

Mam tu tri vritualni servery, ktere bezi v nejakem "cloudu" zalozenem na 
VMWare (nemam pristup k informaci o verzi) a na vsech trech se denne 
objevuje asi 30x problem:
em0: Watchdog timeout -- resetting

System je FreeBSD 10.2-RELEASE-p10 amd64 GENERIC

Sitovka v dmesg
em0: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> port 
0x2000-0x203f mem 0xfd5c0000-0xfd5dffff,0xfdff0000-0xfdffffff irq 18 at 
device 0.0 on pci2

Sitovka v pciconf
em0 na pci0:2:0:0: class=0x020000 card=0x075015ad chip=0x100f8086 rev=0x01 
hdr=0x00

     device     = '82545EM Gigabit Ethernet Controller (Copper)'
     class      = network
     subclass   = ethernet

Sitovka v ifconfig
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>

S watchdog timeoutem jsem se setkal naposledy snad v dobe FreeBSD 6 u 
sitovek Broadcom. U Intelu a jeste k tomu virtualnich jsem tohle nezazil.
Setkal jste se s tim nekdo? Co pripadne vyzkouset za zmeny nastaveni?
