Same issue here on a Thinkpad P50, although I don't see any iwlwifi crash in the logs. Going back to the 4.10 kernel from Zesty fixes the problem.

Upgrading to artful kernel 4.13.0-11.12, there are severe Bluetooth audio issues which have manifested in a variety of weird ways: 1) Playback would stall after 10-20 seconds 2) Upon removing the device and attempting to redo pairing, no devices could be found to pair with 3) After the device ended up reverting to low quality mono HSP mode, it could not be switched back to A2DP This is all rather vague - sorry - but it felt better to get notice of this regression into the bugtracker sooner rather than later.
