T45 restart reason is Skylake(GPU) drivers; 1.I debug the suspend process and find it's OK if just dpm_suspend() return error. Then I catch the lask kmsg when die and it's Skylake's driver. 2.when I rm /lib/modules/4.4.10-android-x86_64/kernel/sound/soc/intel/skylake/snd-soc-skl.ko and snd-soc-skl-ipc.ko,echo mem > /sys/power/state,t45 won't restart. So it can show that suspend skylake failed and restart. 3.I will analysize the driver and try to get some patch.
