Frew Schmidt, please address all of the following: 1) Could you please execute the following via a terminal to attach debugging logs: apport-collect 1767452
2) The next step is to fully reverse commit bisect from kernel 4.16.6 to 4.17-rc3 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions, or providing a commit from a kernel version bisect is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. ** Tags added: kernel-fixed-upstream kernel-fixed-upstream-4.17-rc3 needs-reverse-bisect ** 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/1767452 Title: kernel oops when I undocked Status in linux package in Ubuntu: Incomplete Bug description: Here's a snippet from the kernel log which I think will make the actual issue clear: Apr 27 09:49:20 caliburn kernel: [ 4558.910412] pcieport 0000:0a:03.0: Refused to change power state, currently in D3 Apr 27 09:49:20 caliburn kernel: [ 4558.917717] xhci_hcd 0000:0d:00.0: remove, state 1 Apr 27 09:49:20 caliburn kernel: [ 4558.917724] usb usb6: USB disconnect, device number 1 Apr 27 09:49:20 caliburn kernel: [ 4558.917725] usb 6-1: USB disconnect, device number 2 Apr 27 09:49:20 caliburn kernel: [ 4558.917774] xhci_hcd 0000:0d:00.0: xHCI host controller not responding, assume dead Apr 27 09:49:20 caliburn kernel: [ 4558.968688] xhci_hcd 0000:0d:00.0: USB bus 6 deregistered Apr 27 09:49:20 caliburn kernel: [ 4558.968694] xhci_hcd 0000:0d:00.0: remove, state 1 Apr 27 09:49:20 caliburn kernel: [ 4558.968700] usb usb5: USB disconnect, device number 1 Apr 27 09:49:20 caliburn kernel: [ 4558.968701] usb 5-3: USB disconnect, device number 3 Apr 27 09:49:20 caliburn kernel: [ 4559.076020] usb 5-4: USB disconnect, device number 4 Apr 27 09:49:20 caliburn kernel: [ 4559.076023] usb 5-4.2: USB disconnect, device number 5 Apr 27 09:49:20 caliburn kernel: [ 4559.123365] usb 5-4.4: USB disconnect, device number 7 Apr 27 09:49:20 caliburn kernel: [ 4559.125340] xhci_hcd 0000:0d:00.0: Host halt failed, -19 Apr 27 09:49:20 caliburn kernel: [ 4559.125343] xhci_hcd 0000:0d:00.0: Host not accessible, reset failed.
