It seems I spoke a bit too soon about everything working. I suspended my machine and now came back after a few hours and it seems the latest patches (well, I only could test the pm code in linus' tree of -34 up to now due to display corruptions so there's a lot of changes since then) in d-r-t killed suspend for me - the machine doesn't come back up and hardlocks. Too bad I can't find anything about it in my logs :( Klaus -- Klaus Doblmann B.A. - http://straightrazorguy.net - FSF member #7570 PGP-Key: http://www.doblmann.de/pgp_key.asc http://twitter.com/klausdoblmann A: Because it messes up the order in which people normally read text.
