Well, since you just said "it failed" without posting any details, I can 
only guess what problems you might be encountering.

In order to get OpenAFS to work with a 2.6.12 kernel with swsusp2, you will 
need to undo a change made by the swsusp2 patches to the last line of 
kernel/power/process.c.  Change

EXPORT_SYMBOL_GPL(refrigerator);

back to

EXPORT_SYMBOL(refrigerator);

Without this change, the OpenAFS module will fail to load.  I reported this 
problem to the suspend2 maintainer a while ago, and while he says he made 
the change, it hadn't been integrated as of 2.1.9.5 (I haven't looked yet 
at 2.1.9.9, which is the latest version available for Linux 2.6.12).


To build against Linux 2.6.13, you will likely need the latest OpenAFS 
release candidate, released today.  Unfortunately, we've just gotten word 
that the source tarball on the web site is broken, so you might want to 
wait a few hours until it's been replaced with a corrected one.
