screen picture when resume hangs with additional debug output (pic2)

This is exactly the same scenario as before. 

But the output of /usr/sbin/resume looks a bit weird to me. After the
compression information there is another line "wrote 501 MB" before it hangs.
What does that mean?

It would be useful to see the output of a successful /usr/sbin/resume operation
to be sure whether that is normal or an indication that things are going wrong.
I could guess this is not the first time such a problem needs to be debugged,
so I would nearly expect that some option exists in either /usr/sbin/resume or
the kernel or both to add a delay right there. Like the resumedelay mentioned
earlier, but for unknown reasons that produced a delay in a different location.
If nobody know what such option could be (or some other debugging hints), let's
see whether I can find time to study the source a bit.
