7.0-RC1 onboard em1 intel pro1000 vanishing occasionally

[Oznon]

Hi all,

I am currently experiencing the same issue as well except this time around
with a Supermicro X7DBU motherboard (Intel® 5000P (Blackford) Chipset). The
identical occurence is happening to me as well so we were wondering if
anyone had a resolution? Possibly an updated driver for the Intel NIC card? 
Anywho, here is a snippet of the a particular error we receive before the
interface disappears:

em0: <Intel(R) PRO/1000 Network Connection Version - 6.7.3> port
0x2000-0x201f mem 0xd8920000-0xd893ffff,0xd8900000-0xd891ffff irq 18 at
device 0.0 on pci5
em0: Using MSI interrupt
em0: Ethernet address: 00:30:48:7f:be:38
em0: [FILTER]
em1: <Intel(R) PRO/1000 Network Connection Version - 6.7.3> port
0x2020-0x203f mem 0xd8960000-0xd897ffff,0xd8940000-0xd895ffff irq 19 at
device 0.1 on pci5
em1: Using MSI interrupt
em1: Setup of Shared code failed

Thanks all,

Guy
