Can you also attach full dmesg of the boot so that we can see the initial PCI configuration? Now all the dmesgs are missing that information.
When it initially works, do you boot with the dock connected or not? -- 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/1825395 Title: thunderbolt / PCIe hotplug gets confused after a few cycles on X1 Yoga 2nd gen Status in linux package in Ubuntu: Confirmed Bug description: I have a Lenovo X1 Yoga 2nd gen along with the Lenovo thunderbolt docking station. Initial connection to the dock works great, but after a few plug/unplug and suspend/resume cycles, the system gets in a state where a reboot is needed to make the dock work. The displayport connection still works so my external monitor gets the right display, but the thunderbolt / PCIe connection does not and so the USB and network ports in the dock aren't usable. I assume it is connected to the kernel messages like [37269.423750] thunderbolt 0-1: new device found, vendor=0x108 device=0x1630 [37269.423751] thunderbolt 0-1: Lenovo ThinkPad Thunderbolt 3 Dock [37270.096713] pci 0000:09:00.0: [8086:15d3] type 01 class 0x060400 [37270.096820] pci 0000:09:00.0: enabling Extended Tags [37270.096975] pci 0000:09:00.0: supports D1 D2 [37270.096976] pci 0000:09:00.0: PME# supported from D0 D1 D2 D3hot D3cold [37270.097068] pci 0000:09:00.0: 8.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s x4 link at 0000:07:01.0 (capable of 31.504 Gb/s with 8 GT/s x4 link) [37270.097187] pcieport 0000:07:01.0: ASPM: current common clock configuration is broken, reconfiguring [37270.108588] pci 0000:0a:00.0: [8086:15d3] type 01 class 0x060400 [37270.108705] pci 0000:0a:00.0: enabling Extended Tags [37270.108865] pci 0000:0a:00.0: supports D1 D2 [37270.108866] pci 0000:0a:00.0: PME# supported from D0 D1 D2 D3hot D3cold [37270.109066] pcieport 0000:07:02.0: ASPM: current common clock configuration is broken, reconfiguring [37270.109147] pci 0000:0b:00.0: [1b73:1100] type 00 class 0x0c0330 [37270.109221] pci 0000:0b:00.0: reg 0x10: [mem 0xbc000000-0xbc00ffff 64bit] [37270.109258] pci 0000:0b:00.0: reg 0x18: [mem 0xbc010000-0xbc010fff 64bit] [37270.109295] pci 0000:0b:00.0: reg 0x20: [mem 0xbc011000-0xbc011fff 64bit] [37270.109499] pci 0000:0b:00.0: supports D1 [37270.109500] pci 0000:0b:00.0: PME# supported from D0 D1 D3hot D3cold [37270.109686] pcieport 0000:07:04.0: ASPM: current common clock configuration is broken, reconfiguring [37270.109724] pci 0000:0a:00.0: devices behind bridge are unusable because [bus 0b] cannot be assigned for them [37270.109738] pci 0000:09:00.0: devices behind bridge are unusable because [bus 0a] cannot be assigned for them [37270.109766] pci 0000:0a:00.0: devices behind bridge are unusable because [bus 0b] cannot be assigned for them [37270.109779] pcieport 0000:07:02.0: bridge has subordinate 0a but max busn 0b [37270.109831] pci_bus 0000:3d: busn_res: can not insert [bus 3d-70] under [bus 07-0b] (conflicts with (null) [bus 07-0b]) [37270.109834] pcieport 0000:07:04.0: PCI bridge to [bus 3d-70] [37270.109843] pcieport 0000:07:04.0: bridge window [mem 0xd4000000-0xe9ffffff] [37270.109848] pcieport 0000:07:04.0: bridge window [mem 0x90000000-0xb9ffffff 64bit pref] [37270.109849] pcieport 0000:07:04.0: devices behind bridge are unusable because [bus 3d-70] cannot be assigned for them ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: linux-image-5.0.0-13-generic 5.0.0-13.14 ProcVersionSignature: Ubuntu 5.0.0-13.14-generic 5.0.6 Uname: Linux 5.0.0-13-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: roland 1690 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Thu Apr 18 09:40:22 2019 InstallationDate: Installed on 2019-03-29 (20 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Alpha amd64 (20190326.2) MachineType: LENOVO 20JGS01000 ProcEnviron: TERM=screen PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.0.0-13-generic root=UUID=323a265b-35d4-4a11-82f0-e47b38cac797 ro quiet splash vt.handoff=1 RelatedPackageVersions: linux-restricted-modules-5.0.0-13-generic N/A linux-backports-modules-5.0.0-13-generic N/A linux-firmware 1.178 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/11/2019 dmi.bios.vendor: LENOVO dmi.bios.version: N1NET45W (1.32 ) dmi.board.asset.tag: Not Available dmi.board.name: 20JGS01000 dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 31 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN1NET45W(1.32):bd03/11/2019:svnLENOVO:pn20JGS01000:pvrThinkPadX1Yoga2nd:rvnLENOVO:rn20JGS01000:rvrSDK0J40697WIN:cvnLENOVO:ct31:cvrNone: dmi.product.family: ThinkPad X1 Yoga 2nd dmi.product.name: 20JGS01000 dmi.product.sku: LENOVO_MT_20JG_BU_Think_FM_ThinkPad X1 Yoga 2nd dmi.product.version: ThinkPad X1 Yoga 2nd dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825395/+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
