Comment 0 for bug 1856872

New laptop that is running Ubuntu Mate 19.10, most everything works out of the box even bluetooth but bluetooth does not resume after suspend. In fact I am unable to restart it and get it to work after a suspend. Wireless resumes and continues to work, just bluetooth fails. After suspend the controller and adapter are not found, restarting bluetooth.service nor restarting network manger solve the issue. After a resume the adapter is not found at all, I have tried to remove the module before a suspend and add it back to no avail, the only way to get it working is to reboot which is a pain.

Please let me know what additional data you may need, posting information below:

Chipset is Realtek RTL8822CE, combined wireless and Bluetooth module

Working on intial Boot:
