Title:
Bluetooth input devices gets stuck for a few seconds after brief
inactivity
Status in linux package in Ubuntu:
Expired
Bug description:
Pair both Bluetooth keyboard and mouse, wait ~10 seconds, and any input via
these Bluetooth devices
takes ~5 seconds to respond, while physically attached touchpad and keyboard
works fine. Each time
the lag appears, the following is appended into `/var/log/syslog` during the
lag, and after which
the input is registered:

(In the above log, `usb 1-12` is known to be a bad integrated webcam. These
logs also show up very
early during boot in every distribution tested.)
Problem disappears if either Bluetooth device is disconnected or if the
Bluetooth settings window
is open. Reproduced with 22.10 install, live USB 22.10, 22.04, and 20.04
(had to workaround a GUI
bug with `bluetoothctl`), but not with Debian 11 live USB and Debian 12
testing install (as of 2022-
01-24).
Kernel versions that I've collected:
- Ubuntu 22.10 install: `Linux xps-7590 5.19.0-29-generic #30-Ubuntu SMP
PREEMPT_DYNAMIC Wed Jan 4
12:14:09 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux`

PREEMPT_DYNAMIC Debian 5.18.16-1
(2022-08-10) x86_64 GNU/Linux`
(Also constant pairing and unpairing (connects for half a second and
disconnects for half a second)
with mouse occurs before and right after log in, not sure if I should file a
separate bug for this.)
