Error occurs when sending mail, so I re-send it again.

Hi All.

We are testing Linux upstream version-4.1-rc2 on Koelsch and Lager.
We found Warning messages of PM after resuming system.
The Warning messages is showed as below:

"WARNING: CPU: 0 PID: 1697 at kernel/irq/manage.c:572

Testing method:
# echo enabled > 
/sys/devices/platform/e6c40000.serial/tty/ttySC0/power/wakeup
# echo mem > /sys/power/state
# Resuming system by a key from keyboard.

We'd like to report this problem first.
There are no warning messages at version v4.0 stable.
so we are looking for the error patch that added between v4.0 and v4.1-rc2.

Best Regards,
Jinso/Cao Minh Hiep.

We'd like to send the details of PM's Warning messages on two Board:
