    Note: that same bug exists/existed on i386 back when NO_HZ was
    introduced (2.6.21?). I still see it from time to time on my Quad core
    system (very rare), but not any more on my Duo notebook where it used
    to happen about 1 in n boots (n < 10).

    AFAICT no fix was ever released for it.

    I *still* get very slow resume-from-RAM quite often here
    (new in 2.6.22 kernel, wasn't there in early 2.6.23-rc*).
    Something eventually times out after a minute or so
    and it comes back. Cannot make it happen reliably,
    unless I'm in a hurry to get something done. :)
    I suspect USB here, probably the same loopy bug that
    we added a "loop limit failsafe" for back in 2.6.21(?).
