We recently upgraded a system from ESXi 5.1 to ESXi 5.5 and following the upgrade the onboard I350 NICs will go offline and won't come back up until a server reboot occurs. The NICs will be operation sometimes for a week, or occasionally it will only stay online for about a half hour. The net-igb is currently 5.2.5
Anyone else run into this issue before following a version upgrade? Thanks in advance.
