Also I am wondering if this is the culprit: [ 111.408064] ACPI Error: [SPRT] Namespace lookup failure, AE_ALREADY_EXISTS (20170831/dswload2-346) [ 111.408078] No Local Variables are initialized for Method [XTBT] [ 111.408080] Initialized Arguments for Method [XTBT]: (2 arguments defined for method invocation) [ 111.408081] Arg0: 0000000003b16caf <Obj> Integer 0000000000000005 [ 111.408087] Arg1: 0000000025f94152 <Obj> Integer 0000000002060002 [ 111.408091] ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20170831/psobject-252) [ 111.408094] ACPI Error: Method parse/execution failed \_GPE.XTBT, AE_ALREADY_EXISTS (20170831/psparse-550) [ 111.408099] ACPI Error: Method parse/execution failed \_GPE.XTBT, AE_ALREADY_EXISTS (20170831/psparse-550) [ 111.408106] ACPI Error: Method parse/execution failed \_GPE._E42, AE_ALREADY_EXISTS (20170831/psparse-550) [ 111.408110] ACPI: Marking method _E42 as Serialized because of AE_ALREADY_EXISTS error [ 111.408113] ACPI Exception: AE_ALREADY_EXISTS, while evaluating GPE method [_E42] (20170831/evgpe-646)

After taking a backup for 16.04 (in case this very thing happened), I installed the daily build of 18.04 as it didn't really make sense for me to hold on to a distro that'll be replaced in a couple of months. I noticed there were a few Dell repositories in sources.list, but non of them have bionic endpoints (only xenial). I copied those, in case they would be useful and went to erasing the disk and installing 18.04. Everything seems to work fine, except the USB / Thunderbolt ports. Nothing I try works, whether it be USB or Thunderbolt 3. If I look in dmesg, I can see the controller is recognising something, but it never lands in userspace: [ 1807.837379] xhci_hcd 0000:39:00.0: Host supports USB 3.1 Enhanced SuperSpeed [ 1807.837410] usb usb4: New USB device found, idVendor=1d6b, idProduct=0003 [ 1807.837412] usb usb4: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 1807.837413] usb usb4: Product: xHCI Host Controller [ 1807.837414] usb usb4: Manufacturer: Linux 4.13.0-25-generic xhci-hcd [ 1807.837416] usb usb4: SerialNumber: 0000:39:00.0 [ 1807.837549] hub 4-0:1.0: USB hub found [ 1807.837558] hub 4-0:1.0: 2 ports detected --- ApportVersion: 2.20.8-0ubuntu6 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2018-01-19 (10 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180118) Package: linux (not installed) Tags: bionic wayland-session Uname: Linux 4.15.0-041500-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip libvirt lpadmin lxd plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1745747/+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
