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)

Had the same issue with OS X 10.10 Yosemite Public Beta on my MacBook Pro 13'' and my Thunderbolt Display. The Solution worked without any other issues for me.

I had similar issues with my MacBook Pro (late 2013) and explored a lot into this problem. Here[0] is a detailed explanation and solution.

I had the same problem described here upon installing Yosemite but I followed Carlos's suggestion to use the network assistant and that worked. It must clear out something low level.

I have had this problem since Mavericks, and now it's the same thing in Yosemite too. I hope this solution works, anyways Apple should do something about it (for example drop the adapter price because it's faulty),
