Comment # 6 on bug 1134865 from Leonardo Teodoro

> somebody is setting your /sys/power/mem_sleep to "s2idle" -- do "cat" on
> that file and try changing it to "deep". Like what's the output of this
> sequence:
> cat /sys/power/mem_sleep
> echo deep > /sys/power/mem_sleep
> systemctl suspend
> cat /sys/power/mem_sleep
> echo deep > /sys/power/mem_sleep
> echo mem > /sys/power/state
all the "cat /sys/power/mem_sleep" outputs "s2idle [deep]" even If I do "echo
deep > /sys/power/mem_sleep" and "echo mem > /sys/power/state" outputs "device
or resource is busy"
