A patch was sent to stable. However, some of the stable kernel versions fail to build with this patch, 3.2.y and 3.13.y for example. This is because the function 'find_trb_seg' is still called by xhci_cmd_to_noop, which is removed from mainline but still exists in the stable kernels. The patch removes the definition of find_trb_seg, which is what causes the build to fail.
I built a trusty test kernel with a modified version of the upstream patch to not remove the find_trb_seg function. If this patch resolves this bug, we can ask the 3.13 upstream stable maintainer to modify the patch similarly as well as ask for an SRU to trusty with the fix. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1350480 Can you give this latest kernel a test and see if it resolves the bug? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1350480 Title: [REGRESSION] Kernel update renders Intel NUC (i5-3427) unbootable with USB devices plugged in Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: In Progress Status in “linux” source package in Precise: In Progress Status in “linux” source package in Trusty: In Progress Status in “linux” source package in Utopic: In Progress Bug description: The latest kernel update in Ubuntu 14.04 LTS (3.13.0-32.57) renders our Intel NUCs unbootable, when we cold boot and have USB devices (keyboard, mouse, USB/Ethernet adapter) connected. The 3.13.0-24.47 kernel does not exhibit this behavior. Our particular NUCs have the i5-3427U processor, which is the D53427RKE board (DC53427HYE kit).
