--- Comment #1 from Thomas Merkel <tm+***@core.io> ---
I basically have the same issue on the Thinkpad X1 Carbon 6th Generation with
FreeBSD-12-CURRENT. But somehow the disconnect and issue happen more often than
only one time an hour, more like every 10 minutes:

If you can assist with "dumping device error log" I could provide that
information as well. It somehow really depends on the access point the notebook
is connected to.
