Hi,
Having just recently put 4 of these in 4 new (identical)
machines (P133's, with Intel 430VX chipset) running 2.1.5R, I'm
experiencing some oddities when transfering files. At the moment they
are being operated in 10BaseT mode, and have -link2 for ifconfig
specified in sysconfig.
On two of the machines, the cards work fine, but on the other
two, when *receiving* data, there are delays every so often of around
1 second, the frequency of which varies, giving transfer rates of
anything between 10k/s, and 500k/s. In all cases data is written
(other than to the other slow machine) at just over 1Mb/s. Reading and
writing to another machine running 2.1.5R with a 3C509 produced the
same results, and the problem seems to be machine rather than card
dependant, as I've tried swapping the cards.
`ifconfig de0' shows the following:
de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 194.125.135.250 netmask 0xffffffc0 broadcast 194.125.135.255
and the boot sequence is as follows:

Has anybody come across this before, or have any ideas. Any
suggestions much appreciated.
