Perhaps a sysctl that turns it off by default might help? > Under CONFIG_PM_DEBUG or so. btw., i think the main problem with debugging is whether one can 'see' the problem, literally. Would it be possible to have a s2ram debug/test mode that puts as much stuff into low-power mode as possible - except for the console. That would still include a fair amount of random drivers that is at issue here. And once the crash/hang happens while it can be seen where it hangs/crashes, it becomes a lot more debuggable IMO. Or is this impossible / not feasible / inefficient?
