Owen Dunn, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-a10 ** Tags added: latest-bios-a10 ** Changed in: linux (Ubuntu) Importance: Low => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1457852 Title: Optiplex 9020 reboots rather than shutting down if USB3 enabled Status in linux package in Ubuntu: Incomplete Bug description: Description: Ubuntu 14.04.2 LTS Release: 14.04 linux-image-3.13.0-49-generic version 3.13.0-49.83 I have a large number of Dell Optiplex 9020 machines, and when they are asked to shutdown with e.g. shutdown -h now, they shut down successfully and then approximately four seconds later they start up again. This problem only happens if the system's USB3 ports are enabled. If I reinstate the code removed from xhci-pci.c in the diff.gz: if (pdev->vendor == PCI_VENDOR_ID_INTEL && - (pdev->device == PCI_DEVICE_ID_INTEL_LYNXPOINT_XHCI || - pdev->device == PCI_DEVICE_ID_INTEL_LYNXPOINT_LP_XHCI)) { - /* Workaround for occasional spurious wakeups from S5 (or - * any other sleep) on Haswell machines with LPT and LPT-LP - * with the new Intel BIOS - */ - /* Limit the quirk to only known vendors, as this triggers - * yet another BIOS bug on some other machines - * https://bugzilla.kernel.org/show_bug.cgi?id=66171 - */ - if (pdev->subsystem_vendor == PCI_VENDOR_ID_HP) - xhci->quirks |= XHCI_SPURIOUS_WAKEUP; + pdev->device == PCI_DEVICE_ID_INTEL_LYNXPOINT_LP_XHCI) { + xhci->quirks |= XHCI_SPURIOUS_REBOOT; } and add msleep(1000) to xhci.c as suggested at http://www.gossamer- threads.com/lists/linux/kernel/1713011 ...shutdown shuts the machine down as expected. I attach the output of lspci -mnn.
