I'm going to play with that testing program further in the > meantime. Do you actually see this with _plain_ 2.6.25? So far I've assumed that all the reports are about post-2.6.25 issues. Also, it does seem like you can re-create this at will in ways that others can not. Could you try to bisect it a bit? Right now we have no real clue what it is all about, except that it seems to be related to suspend/resume and there are some indications that it's about networking (and _perhaps_ wireless in particular).
