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. /Peter > >> But this only seems to happen after the tpm module has been unloaded >> when >> going to sleep.
