[arch-general] Hibernation not working

[Tim Ye]

I read a web page sometime ago says these would work:

  - put your computer into "sleep" (to RAM):
    $ sudo su -c 'echo "mem" > /sys/power/state'
  - put your computer into "hibernate" (to disk):
    $ sudo su -c 'echo "disk" > /sys/power/state'

I just tried both, but "hibernate" doesn't work on my Archlinux but 
works on Debian (with an older kernel) on my laptop.
