Description Len Brown 2014-06-10 15:29:36 UTC

# echo freeze > /sys/power/state

use power button to wake system

result:

system wakes up
GUI (say, on Ubuntu 14.04) will ask if I want to reboot or poweroff

desired result:

system wakes up w/o asking about poweroff

I think we can fix this in ACPI button driver to send a pm wakeup event only, i.e, do not send input and netlink event for a power button express during freeze mode, just like the trick we do in drivers/acpi/sleep.c for S3.
What do you think?
