Android Device reboots as soon as it goes in suspend state

Question

I'm porting Android Lollipop on x86_64, seeing one weird behavior from device.

As soon as device goes in suspend state it reboots the device.

Please help me to investigate the reason behind it, what all the possible methods to reboot the device without using power button (i.e. from kernel code, android framework).

After lot of research, what all I can conclude is, that this issue was caused by unsupported sleep state provided by ACPI.

Restarting automatically can be down (but not limited) to a few different things:

1. WiFi related
2. Lock screen related
3. Storage related - Some users report that a low internal storage was the cause of this, and simply freeing up some space fixed this
4. Battery related - Malfunctioning or insufficiently charged battery
5. Power button related - Many report that dirty can get stuck under the power button, triggering the button randomly. Pressing it in hard can remedy this

On top of these known reasons, it seems that this is a recognised problem with the Lollipop update.

I'm also facing the same issue (restart when phone locks, red.) however if I set the other security type except pattern the problem is solved. If we use PIN or NONE then the problem will solve, the problem is with Pattern security type only.
