[dothiko <dothiko@xxxxxxxxx>]

sorry,and thank you for telling me how to report kernel suspend
problem,penalvch.

in my resume-trace dmesg.txt,

from [   89.386795] , entered S3 suspend  with ' sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" '
and PC  slept successfully,then resumed with powerbtn manually, as usual.

from [  155.529084] , mount/unmount USB3.0 HDD to trigger/reproduce
problem

from [  194.783961], entered S3 suspend again -> unintentionally
immidiate resume

note: I switched video card from NVIDIA(GeForce GT640/gk208) to Intel HD
2500 IGP because NVIDIA card cannot work with kernel 3.19,but nothing
changes about suspend/resume problem of Asrock H77M.
