The user run application 'mc' (Midnight Commander) was blocking hibernation (and now I see there was another application named 'pool'). I tried to kill 'mc' with killall -9. It still refused. I killed the terminal that had it, no way. In the end, I had to poweroff the machine instead. I think that mc was blocked because it had open a remote directory externally: sshfs cer@192.168.1.134:/ ~/fusermount/ and that other machine had been hibernated a minute before. How can it be that a plebeian app stops the almighty kernel in its tracks? - -- Cheers Carlos E. R.
