CPU Wakeup is not working from standby mode

[titusece]

Hello, Thanks for your driver. Its really useful. I am facing one issue is that I am unable to wakeup from sleep/standby mode. But I am able to wakeup from standby mode if I have not inserted this timer counter kernel module driver into system.

Standy mode: echo standby > /sys/power/state

What could be the issue ? Any hint or insights on this ? Thanks again!
