Обновление как раз случилось 18 мая (скачок во времени: смена часового пояса с разницей в 14 часов) и поплыло: вкл-выкл, выкл-вкл.

К сожалению, гугл даёт много булшита, кроме этой ветки форума: https://bbs.archlinux.org/viewtopic.php?id=236479
Изучение показало: виноват параметр модуля btusb - enable_autosuspend. Его установка по умолчанию зависит от параметра ядра CONFIG_BT_HCIBTUSB_AUTOSUSPEND, вот как это выглядит в
коде:
static bool enable_autosuspend = IS_ENABLED(CONFIG_BT_HCIBTUSB_AUTOSUSPEND);
А в манжаро какого-то чёрта эту опцию включили:
$ cat /lib/modules/4.15.18-2-MANJARO/build/.config | grep CONFIG_BT_HCIBTUSB_AUTOSUSPEND
$ cat /lib/modules/4.16.8-1-MANJARO/build/.config | grep CONFIG_BT_HCIBTUSB_AUTOSUSPEND
CONFIG_BT_HCIBTUSB_AUTOSUSPEND=y
Видим: в 4.15 - нет, в 4.16 есть и включена.
Выключаем опцию на лету:
echo N | sudo tee /sys/module/btusb/parameters/enable_autosuspend
И перманентно, создаём файл /etc/modprobe.d/btusb.conf со следующим содержимым:
options btusb enable_autosuspend=n
Перед 23 мая были сделаны данные изменения и из лога видно, как изменилось поведение: один раз мышка нашлась когда пришёл и включил на работе, второй раз - переподавал питание на модуль Bluetooth.
Материалы:
- https://ljn917.wordpress.com/2018/03/01/disable-bluetooth-autosuspend/ - тут можно взять идею селективного управления автозасыпанием
- https://bbs.archlinux.org/viewtopic.php?id=236479 - собственно решение
- intel 8265 bluetooth no longer functions as of 4.16 - тут всё понятно
