[tulip-bug] Problems with kne111tx
Sun, 19 Aug 2001 17:50:34 +0100
I'm running a linux router/server off my cable modem, and I've been
having a little problem with it. The two network cards in it are both
KNE111TX's, and it seems that if traffic flow goes anything higher than
about 100 kb/s (rough guess, figure may be higher, but the value is
significantly lower than what the 10mb network can do) that we get a
collision light on the hub, and also tcpdump reports my computer waiting
for a sequence number that the server does not ever give out until it
times out for the server to respond, with no luck. The first few packets
get through, but then everything messes up.
In other words, traffic to/from the 'net is fine, but any sort of file
transfer across the LAN is impossible. I've tried using several
different protocols (SMB, HTTP, FTP), all with the same results. The
server talks to the LAN fine at low speeds, but once we get to anything
higher, it cuts off. One example was with telnet, normally fine, but it
cut out when I was cat'ing my /var/log/messages, because of the data
flow rate exceeding temporarily whatever the limit is.
I'm using a 2.4.9 kernel (same problems earlier with both 2.4.4 and
2.4.7). This did have the 0.9.5-pre16 tulip driver, and I'm now trying
the 1.1.8 driver, same results with both. I've also tried this with
another computer on the LAN, same results there. My system is running
Windows '98, the other test system was running Windows Me.
Any ideas? Because this is me completely lost here.
