Thank you for your bug report. Could you add your 'journalctl -b 0' from
a session having the issue?
Could you also do 'apport-collect 1871695' to include debug logs to the
report?

Title:
Bluetoothd uses 100% of a CPU thread
Status in bluez package in Ubuntu:
Incomplete
Bug description:
Hi,
I have a bluetooth keyboard that I use for my laptop, which runs
Kubuntu 19.04. I noticed though, that a short while after connecting
the keyboard, the CPU fan goes on and one of the threads is at 100%.
If I open a terminal and type "top", it shows that a process called
bluetoothd is taking 12% of the CPU power which is a full thread
(100/8=12.5). I'm not sure what it's doing, but it doesn't require
that much CPU power to work. If I end the process and restart it, the
keyboard works fine and the CPU is calm until it happens again (about
20 minutes later). I reinstalled bluez and even tried recompiling from
source, but the problem persists.
My specs:
Version of bluetoothd: 5.50
Linux Kernel: 5.3.0-46-generic
KDE Plasma Version 5.16.5
Thank you,
Isaac Cohen
