Helo Timo. Just so I understand, are you saying that when running
with this patch, it works fine in daily use, but flood ping fails? Or, are
you running without my patches? What kind of switch/hub are you connected
to?
-thanks

} hi,
}
} sorry for replying late; i fiddled around a lot and it seems that

}
} i have one machine in a rack hosting company with nearly the same config
} as the machine here. the remote machine runs 3.0-RELEASE. it's connected
} to a D-Link switch and runs fine, wrt our topic that is i can ping flood
} _from_ that machine without losing packets.

} trying it on the (nearly same configured) machine here, i get dropped
} packets with 3.0-RELEASE as well as a 3.0-STABLE from late march and
} 3.0-STABLE from yesterday, with your above patch applied.
