Update: rebooted the system, doing just suspend_stress_test - and that causes a restart. 

for 8578.0.0 'suspend_stress_test -c 1' separately works for me.

I still see original (dark resume) failure however.


just simple echo mem > /sys/power/state make host unrecoverable (resume fails).  Need to connect servo as there's nothing in ramoops to debug and I'm having to long-press power to shutdown and then power back on.

and in this case I saw a reboot instead of a hang.
