    xHCI host controller not responding, assume dead; HC died; cleaning up

    After upgrading the kernel to 5.0.0-15-generic, my usb and bluetooth devices would randomly stop working. Re-attaching, or reconnecting bluetooth devices doesn't help. Only restarting the laptop would help to recover connections. However, after a week or so, even if all usb/bluetooth devices work, when I turn the laptop off, it just doesn't. Instead, it gives the following message:


    Code:
    xHCI host controller not responding, assume dead
    HC died; cleaning up
    The laptop would not turn off and had to manually be turned off pressing the power button.

    I have no idea what is going on so all suggestions are welcome. It happens with both Ubuntu 19.04 and Pop OS 19.04.

    Thanks.

    Give us the snapshot of /var/log/syslog for the new 5.0.0-15 kernel.
    And then boot the system with the old kernel and upload the /var/log/syslog here.
    Without this information it is as difficult as playing chess with grandmother.

    Which part would be useful? The files are huge.

    Especially when you get freeze, copy-paste the last 20-30 lines of each log - that should be ok.

    You can use https://pastebin.com/ which might be easier and faster than uploading text here.

    The output of "lspci -nnvv" might be helpful as well.

    Apparently NVIDIA driver is keeping your CPU busy in 5.0.0-15. This can be seen in the log.

    There are 3 workarounds proposed here:

    Can you give a try?

    Thanks. I removed the NVIDIA driver. So far, so good.
