IbeeX, thank you for reporting this and helping make Ubuntu better. 1) Could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description)?
2) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 3) In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel 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 issue 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 X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, 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. Also, you don't need to apport-collect further unless specifically requested to do so. Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results. Thank you for your help. ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** 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/1599476 Title: Thunderbolt hotplug causes system hang Status in linux package in Ubuntu: Incomplete Bug description: Description: Ubuntu 16.04 LTS Release: 16.04 Hot-plugging Dell's WD15 Thunderbolt cause a system panic with regular kernel 4.4.0-28. Using http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.6.3-yakkety/ kernel. WD15 works if it is connected to laptop during boot time. Hot-plugg causes system hang What you expected to happen: Hot-plugg WD15 thunderbolt (http://www.dell.com/support/article/us/en/04/SLN301105) all features should work (USB, sound-card, port replication...) What happened instead: Display port on WD15 works, USB replication don't work sound-card don't work and eventually system hangs. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 DistroRelease: Ubuntu 16.04 InstallationDate: Installed on 2016-05-04 (63 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) NonfreeKernelModules: nvidia_drm nvidia_modeset nvidia Package: linux (not installed) Tags: xenial Uname: Linux 4.6.3-040603-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1599476/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
