==Bug detailed description==
I tried suspend/resume with S3 for several and found system hangs.
Saw the same issue when suspend/resume with S4.
Will try to capture dmesg and bisect next work day.

==Reproduce steps==
1. Boot and login
2. echo mem > /sys/power/state
3. Click keyboard key to resume
4. Repeat step 2,3 for several times, system hangs.
