I suspend those long delays may have something to do with USB, as it takes longer for my hub + mouse to come back to life during the sequence. But I have since then re-applied the powertop patches, and the long delays vanished. Back with -rc9 I normally also had those powertop fixes, and so this problem could be much older and was never noticed until I ran without them. I'm no longer actively investigating, as the delays are gone (powertop patches), and the crashes are much less frequent since patching. Cheers
