Public bug reported:

It looks to be a duplicate of
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1416557 bug (which
was closed because it has expired).

I made kernel bisection (log attached) as was requested in bug 1416557 and found
# first bad commit: [faae404ebdc6bba744919d82e64c16448eb24a36] ACPICA: Add "Windows 2013" string to _OSI support.

It appears that resume fails because ACPI OSI reports OS to be "Windows 2013".
I added boot kernel parameter acpi_osi="!Windows 2013" and now able to suspend-resume normally (checked in kernels up to 3.16)

I have no idea whar ACPI OSI means and why  "Windows 2013" prevents from
normal resume (the problem seems to happen somwhere in nouveau driver).
I just spend 3 days for this bisection and want others ubuntu users have
this problem  fixed.
