Mavericks installed, now thunderbolt ethernet doesn't online after waking from sleep
Mid 2012 Retina Macbook Pro, 15 inch - as title suggests, after recently installing Mavericks from the app store + doing an upgrade install, the thunderbolt ethernet adapter no longer comes back online after the laptop wakes from sleep. System Information shows that the device is present and connected, it just won't bring the network interface up, so I have to disconnect + reconnect the adapter to get networking back up.
Wifi works fine, no problems there.
Anyone else encountered a similar issue?
MacBook Pro (Retina, Mid 2012), OS X Mavericks (10.9)
