Thanks again for testing, Mark. I've created on more test kernel. This kernel makes no changes to the igb code at all. So if the bug does not exist with your current up to date kernel, it shouldn't occur with the test kernel.
Could you and any other folks affected by this bug test my new test kernel? It can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1454892/lts-backport-utopic/ Note, with this test kernel you would need to install both the linux- image and linux-image-extra .deb packages. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-utopic in Ubuntu. https://bugs.launchpad.net/bugs/1492146 Title: igb Detected Tx Unit Hang Status in linux-lts-utopic package in Ubuntu: Confirmed Status in linux-lts-utopic source package in Trusty: Fix Released Bug description: Hello!
