Public bug reported:
Description: KDE neon User Edition 5.21
Release: 20.04
linux-image-5.10.0-1014-oem:
Installed: 5.10.0-1014.15
Candidate: 5.10.0-1014.15
Once in a while (typically once every 10 minutes or so) my Bluetooth Apple
Magic Mouse (I gen) disconnects and reconnects again leading to the "magicmouse
0005:05AC:030D.001E: unknown main item tag 0x0" messages in the kernel log. But
this time it seems to have caused a crash in the Bluetooth stack. Here is the
dmesg output:
