    Subject[BUG][2.4] /proc/kcore is a random generator ?
    Hi all,

    I'm encountering a rather strange behaviour here with 2.4.25 on a P4 HT,
    even when I boot it with "nosmp" :
    - du /proc/kcore says '525255' (I have 512 MB RAM)
    - if I do it again many several times, sometimes it says '0'
    - after a moment (or several tests, I don't know), it stabilizes to some
    value (either 0 or 525255).
    - then, just starting vmstat, or logging into the system is enough to
    make it switch to the other value.

    At first, I had the feeling that it displayed '0' when I have an even number
    of processes, and 525255 when I have an odd number, but it's not even the case.
    Once it doesn't move by itself, a few fork/exec are enough to switch the value.

    If I boot in HT mode, sometimes I can reliably make it display 0 and 525255
    alternatively, just as if the pid parity or CPU number was involved in the

    Update: same results with 2.4.26-pre1. du from coreutils 4.5.4 and 5.0.

    This is amazing. Did anyone notice this ? A friend just told me that plain
    2.4.22 on his notebook does the same !
