prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.6 kernel[0].

tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:

Thanks in advance.

  Thunderbolt 3 USB-C Port not "hotpluggable"

Status in linux package in Ubuntu:

Bug description:
  I have a Dell Precision 5510 with 16.04 Beta 2. The Thunderbolt3 port
  will provide power to devices, but will not recognize them when
  plugged in after boot.

  If a Thunderbolt USB-C to Ethernet adapter is plugged in on boot, the
  device is recognized and usable as an ethernet connection. However if
  it is removed and plugged back in, it is not recognized when

  I also have a Nexus 6P Android phone with USB-C. The laptop will
  provide power to the phone but will not recognize it as a connected
  device, even when attached at boot. This may be a related issue or
  something else entirely, but wanted to pass along none the less.

  I do not have any other USB-C/Thunderbolt adapters to test with at
  this time.
