It's probably best to perform a reverse kernel bisect to figure which commit fixes this issue.
One question, does this issue only happen after undocking then trying to use ethernet? Does it happen if you perform a cold boot without using the dock? Also, can you test the latest upstream 3.8 stable kernel, just to confirm it's not fixed there yet: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.8-raring/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169244 Title: Thinkpad ethernet unavailable after undocking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1169244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
