    Hi.

    I've a problem with my server/router, that I've seen on
    various kernels. currently I'm running 2.4.21, but I've
    seen the problem on 2.4.20 and 2.5.70, too.
    I'm using a 3com 3c509 ISA ethernet card.

    When this server stays a longer time (about one night, 12 hours)
    without network-traffic, it seems like the whole network-interface
    falls into a very deep sleep. It's very hard to wake the machine
    up.
    Today it was _very_ hard. First I tried to reach the internet
    through this machine (it's a router), but it didn't work.
    Every packet was thrown away by the router.
    Then I tried to login via ssh into the machine, but I got
    no response. Then I tried to ping the machine. All packages
    got lost. But after a few minutes of pinging, suddenly the
    machine responded in normal speed. From now on ssh and
    routing was possible too.
    It's like I have to tickle the machine a bit, before its
    network-interface wakes up and I'm able to transmit some
    packages.

    I've no idea for the reason.
    Thank you for every help.
