blocos de processo i3pystatus-python suspender e desligar

1

Depois de usar meu sistema arch-linux um tempo decente, pode acontecer que o processo do i3pystatus não seja mais freezable. Como resultado, não posso mais suspender meu laptop. Matar o processo (killall -9 python) não tem nenhum efeito: o processo reside como um zumbi. Até mesmo o desligamento não funciona mais. Ele pára e aguarda esse processo para sempre.

    -- The system has now entered the suspend sleep state.

O mesmo aconteceu comigo quando usei o i3status em vez do py3status (mudei para py3status para superar esse problema). Alguma idéia do problema e como rastrear o bug?
