Hi, I am on 8.2, and I see that the link on the 1G ports is constantly
bouncing. I have verified cabling etc, and this is seen on multiple
setups.
The NIC exhibiting this is:
em1@pci0:8:0:1: class=0x020000 card=0x11a48086 chip=0x10a48086 rev=0x06 hdr=0x00
vendor = 'Intel Corporation'
device = '82571EB Gigabit Ethernet Controller'
class = network
subclass = ethernet
em2@pci0:9:0:0: class=0x020000 card=0x11a48086 chip=0x10a48086 rev=0x06 hdr=0x00
vendor = 'Intel Corporation'
device = '82571EB Gigabit Ethernet Controller'
class = network
subclass = ethernet
