Dear all,

I am using a box with 2.4.5-ac14, 3c59x eth0 driver, 3c905C network card.
When working with it, the network has been behaving ok. Now I ping it from
a remote location, and I see the following strange effect:

After a few seconds, only every fifth ping gets back! (quite
exactly, reproducible). Ping output attached.

Another box on the same hub responds totally normal, so it is no network
congestion. I cannot ssh in at the moment, unfortunately. I tried several
different ping source machines, running 2.2.14(SuSE71), 2.2.14 SMP
(vanilla+int.crypto), 2.2.19, and a SPARCstation - they all give basically
the same result.

(Well, besides the target machine is one of these still constantly logging
"clock timer configuration lost - probably a VIA686a motherboard".)
