s2disk support: everything works but S4 aborts with no error message

[Marc MERLIN]

Is there a correct list suspend to disk nowadays? All places I looked at
seem deprecated.

Thanks,
Marc

First, I apologize for Emailing you directly. I just spent 1H going
through uwsuspend pages to try and get the proper support channel, and
all I find is stuff about s2ram not being supported anymore and nothing
for s2disk.
The sourceforge mailing list looks like it's just spam now.

Could
http://suspend.sourceforge.net/index.shtml
and
http://en.opensuse.org/SDB:Suspend_to_disk
be updated?

Now my question: My W500 thinkpad used to suspend to disk fine, ans
suspend to RAM still works fine.

Nowever, now suspend to disk goes through all the motions and then at
the last minute aborts with no error message I can find:

It fails here, but I don't know why, and then it resumes.

Any idea how I can debug further?
