Public bug reported:
Hi,
I know that ubuntu does not support the use of the hibernation feature
found in the linux kernel. However, I would like to point out that on
my system (a Phenom system with ASROCK motherboard) hibernation worked
perfectly on all ubuntu versions, but is now broken on precise.
Asked to hibernate, the system does everything it should and shuts down,
to immediately restart by itself a second later. When system restarts,
it perfectly resumes from the hibernation image. I suspect this is a
regression in the 3.2 kernel wrt 3.0.
If the ubuntu kernel team does not want to look into this, please at
least propagate all the relevant info upstream. Hibernation is
important to some: (i) some desktops still consume a ton of power in
suspend mode and (ii) some laptops (notably the eeepc) do not last more
than 24-36 hours in suspend mode because the battery is very small.
Hence, if you suspend them and forget to wake them up in time you
certainly experience data loss from the running apps that might have
unsaved stuff.
