Code instrumentation by outb(XX, 0x80) usually caused the issue to disappear. However I found out that it's caused by might_sleep() calls in flush_workqueue() and flush_cpu_workqueue(). I.e. it looks like there is a task which deadlocks/spins forever. If we won't reschedule to it, suspend proceeds. I replaced the latter might_sleep() by show_state() and removed refrigerated tasks afterwards. The thing is that I don't know if the prank task is there. I need a scheduler to store "next" task pid or whatever to see what it picked as "next" and so what will run due to might_sched(). I can then show it on port 80 display and read it when the hangup occurs. Depending on which might_sleep(), either flush_workqueue() never (well, at least in next 5 minutes) proceeds to for_each_cpu() or wait_for_completion() in flush_cpu_workqueue() never returns. It's a regression against some -rc1 based -next tree. Bisection impossible, suspend needs to be run even 7 times before it occurs. Maybe a s/might_sleep/yield/ could make it happen earlier (going to try)? Attaching the filtered show_task() output: PM: Syncing filesystems ... done. Freezing user space processes ...
