Got the same issue on 5.2 5.3 and 5.4 rc kernels.
The BT part of my Intel 8265 wifi/BT card of my matebook D14 laptop is kicked
out after a few minutes of use with a logitech anywhere mx 2s mouse.
Only a hard power off resolve the issue. reboot does not revive the
adapter.

Kai-Heng,
Actually, I saw that the fix just landed in bionic-proposed in version
4.15.0-46.49 on 2019-02-15, so bionic-updates and bionic-security don't
have the fix yet as of today.

I don't see "xhci_hcd :00:14.0: xHCI host controller not responding,

I reproduced the same(?) issue by passing by passing an usb controller
to kvm.(https://www.redhat.com/archives/vfio-
users/2018-February/msg00030.html) When I shut down the virtual machine
and try to start again it always fails. Tested your kernel and still the
same issue. Hope this helps.

This seems similar indeed, although I don't have any thunderbolt
