Public bug reported:

The patch provided in upstream bug
<https://bugs.freedesktop.org/show_bug.cgi?id=52572> and implemented
through 28-suspend-hybrid.patch causes error messages "sh: I/O error"
when resuming with suspend-hybrid and hibernate kernel methods.

With suspend-hybrid it also forces the hibernation mode, as shown in
/sys/power/disk, to "suspend" instead of restoring the original mode
which is what the patch tried to do.

Please see the upstream bug for a review of the provided patch with
proposed fixes.

Affects all Ubuntu and derived versions with pm-utils
1.4.1-9fix.ubuntu12.10 or later.
