Very interesting indeed.

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).
