Is the crash you see something different from the hang? If you can catch
that with the backtrace and the register dump it should help.

Couple of additional steps to try:

- Unplug monitors from the dock and see if that makes it work (assuming
  you have monitors connected).

- Disable PCIe tunneling and see if that makes it work. This results
  that the PCIe devices on the dock are not functional but it can point
  us to the direction. You can do this on regular distro (Ubuntu, Fedora
  etC) like:

    $ boltctl config auth-mode disabled

  Or got to "Settings" -> "Privacy & Security" -> "Thunderbolt" and flip
  off the "Direct Access" switch.

Sure.
