  • Bug#265327: /proc/sys/net/irda/max_baud_rate: No such file or directory

    From Mark Lanett@1:229/2 to All on Thu Aug 12 20:00:12 2004
    From: [email protected]

    Package: irda-utils
    Version: 0.9.16-4

    Upon startup I get this message:
    Starting IrDA service: /etc/rc2.d/S20irda: line 35: /proc/sys/net/irda/max_baud_rate: No such file or directory

    However when I check, /proc/sys/net/irda/max_baud_rate does exist. There
    must be a race condition somewhere.

    /etc/init.d/irda does this:
    echo "115200" > /proc/sys/net/irda/max_baud_rate

    but I find that cat /proc/sys/net/irda/max_baud_rate gives me
    16000000

    Anyway I believe a tiny little patch would be:
    test -f /proc/sys/net/irda/max_baud_rate && \
    echo "115200" > /proc/sys/net/irda/max_baud_rate

    This is not really correct but I doubt any device will negotiate a speed
    higher than 115200 anyway.

    actually, there already is a little delay with "sleep" in the
    init-script (beginning with version -5 which is in unstable). could you
    please put a

    sleep 1

    before the echo into max_baud_rate and tell me if this works for you,
    then? and please close the bug (or tell me to do so) if it works.
    the problem with your test is that the echo might not happen and
    this would go unnoticed, although it is perhaps necessary for your
    machine. it might be better to let the warnings come through.

    cheers,
    sebastian
