I have also played around with the /sys/power knobs: Running through /sys/power/pm_test states, it appears that the hangs start occurring when pm_test is set to "processors". Trying to use pm_trace did not point out a specific module. Setting pm_async to zero has allowed me to do a fair number of suspend-resume cycles without experiencing a hang (yet), will update... Setting /sys/power/pm_async to 0 has allowed me to successfully suspend my system for more than a week now. I'll try to do a bisect soon between 3.16.1 and 3.16.2. Any news on the bisect result? |
