    I can reproduce it and Peter's patch does fix it for me.

    e.g.
    root@earth:/sys/devices/system/cpu/cpu1# time echo 0 > online
    real 0m6.743s
    root@earth:/sys/devices/system/cpu/cpu1# time echo 0 > online
    real 0m7.770s

    I've observed delays from ~3 s. up to ~8 s. (out of ~20 tests) so the
    10s. delay of msleep_interruptible() might be related but
    I'm still looking for the reason why this fix helps (and what goes
    wrong with the current code).
