Hmm, that's strange that they don't boot. Can you also test the latest Trusty kernel from: https://launchpad.net/ubuntu/+source/linux/3.11.0-12.19/+build/5088396
There are some hints on how to get further debug info from a boot failure at: https://wiki.ubuntu.com/DebuggingKernelBoot As mentioned on the wiki, it would be great if you can attach a log file which may have captured any messages you see. If you are unable to capture a log file, a digital photo will work just as well. As a last resort you can even copy messages down by hand. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1245938 Title: Intel x520 NIC's (ixgbe) stop working in 12.10, 13.04, 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1245938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
