Sadly I don't know. Reinserting the module after a resume doesn't 
really seem to do much, for instance it doesn't recreate the directories 
I listed/cat above.

But since one of the messages is after 4320 (seconds?) I guess it must 
be something like that. But I didn't see them when I tried modprobing 
the module several times, to get the directories in /sys/ back.
