[Bug 1768852] Re: Kernel bug when unplugging Thunderbolt 3 cable, leaves xHCI host controller dead
Thanks all for working on this. I've been trying to nail down the issues on my Thinkpad X1 Carbon for a couple of weeks and this seems to be the solution. I'm a little unclear from the bug report when this bug fix will be released, will it be in July with the 18.04.1 update? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768852 Title: Kernel bug when unplugging Thunderbolt 3 cable, leaves xHCI host controller dead To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1768852] Re: Kernel bug when unplugging Thunderbolt 3 cable, leaves xHCI host controller dead
Just want to confirm that this fixed the problem for me as well. And just to be absolutely clear, here are some of the problems I was having when attaching/detaching Thunderbolt 3 on my XPS 13 9360: 1) Re-attaching the dock, USB would not function 2) Unable to suspend, reboot, or shutdown after detaching the dock 3) Eventual system hang/freeze 4) Occasional black screen in KDE After running this kernel for a bit, it seems all of these problems are gone. Looking forward to having the patch merged! For what it's worth, I began having these issues on the KDE Neon distribution sometime after the 4.10 kernel was released. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768852 Title: Kernel bug when unplugging Thunderbolt 3 cable, leaves xHCI host controller dead To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
