(Get the code!)
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.
