I'm not having much luck though, so I need some pointers on how to debug this. The symptoms are that the machine shuts down when suspend is triggered and wakes up when the power button is pressed or an usb device pokes it. Unfortunately it never gets back to a running state. It rattles a bit on the disk, powers up the fans and turns on the LEDs, but that's it. Doing a suspend in Windows has entirely different behaviour. There it keeps all fans running, and doesn't do much in the way of saving power. It goes from 90 W to 67 W from idle to "standby". The [broken] state Linux puts the system in OTOH runs at 13 W ("off" is 10 W). I've been trying to use pm_trace to debug where things lock up, but I'm not able to get it to work. I do "echo 1 > /sys/power/pm_trace" and then suspend the machine. But at the next boot, the clock is still sane so it seems like the PM code never stores anything.
