No idea in general, but I made some tests.First, it kind of worked: after restarting the computer, I got error messages in dmesg like the following:

Only WLAN was still not working, unplug/plug the USB stick did make it work again.
Then I modified my test script to set the wake-up time and disk > state but then my computer froze (see attached picture). After reboot, I tried again, shutting off nodm (for vdr-sxfe) and vdr before calling my test script. And the computer woke up!

Sounds promising, thanks for this. I thought nevertheless that disk suspend doesn't have a special power state but is just a special way to shutoff and reboot. Am I wrong? Could the "shutoff" method of disk suspend be copied to normal shutdown?
Thanks already, I feel better :-) Eric
