Mismatched suspend2 interfaces == Suspend was aborted

[Andrew Haninger <ahaning@gmail.com>]

I'm having an odd problem with software-suspend recently. Running the
latest kernel/suspend2/hibernate, I'm getting an error which is
confusing me:

WARNING: The suspend2 scriptlet was written for a different suspend2 interface
         version from the one in your running kernel. This scriptlet was
         written for version between 15 and 15 where as the version running
         in your kernel is 16. Things may not work as expected, but proceeding
         anyway ...

 - hibernate: Suspend reported the following errors:
Suspend was aborted (see dmesg).

"written for a version between 15 and 15" is the part that is
confusing me. First, version 15 of what? Second, between a version and
itself?


So, I look at dmesg. Here's the stuff it says to give when reporting
bugs (plus some extra stuff):

Software Suspend 2.1.9.5: Initiating a software suspend cycle.
Software Suspend 2.1.9.5: Swapwriter: Signature found.

I've tried removing /etc/hibernate and /usr/local/sbin/hibernate and
reinstalling hibernate script 1.08, but I still get this error.

I think this might have something to do with the new movement to the
cryptoapi and there's just something I'm not getting.

Anyway, here's my bug report. Thanks.
