Laptop cannot wake up after suspending while connected with bluetooth

If I suspend my laptop while it is connected to my Wacom tablet with bluetooth, it cannot wake up back.

The Wacom tablet driver is xf86-input-wacom if relevant.

Very difficult to debug, likely a firmware bug in your wireless adapter. I would try the following: See if you can safely stop and restart bluetooth while the tablet is connected:

# systemctl stop bluetooth.service
# systemctl start bluetooth.service

If that works without crashing, add these commands to the pre-suspend / post-wakeup scripts. Have a look at the powerManagement module options on how to do that.

This problem seems to have gone after an update a while ago.
