Hello,
Trying out the 2.5.64 kernel to try to solve some IDE specific
problems with 2.4.x kernels. Now I have another problem. We have a
Windows LAN and a Windows XP with WinRoute Pro as gateway.
When booting the linux-machine with the 2.5.64 kernel the windows
machine goes to 100% cpu and the switch (Dlink) goes crazy (loosing
link, other machines get 100k/s instead of 10-12MiB/s etc).
I compiled the 2.5.64 with as few options as possible, no
netfilter, or IPSec or similar stuff.
What can be the problem?

Forgot to say I am using a Intel Pro100+ NIC and I have tested with
both the Becker driver and the Intel driver.

I've seen something similar [1] happen to a LAN with one Windows XP machine
running vcool: http://vcool.occludo.net/ . This is also available for Linux
(http://vcool.occludo.net/VC_Linux.html). Are you running this patch or a
similar one?
[1] all machines were seeing frame errors on packets > 250 bytes; it was a
10 mbit coax lan.

Nope, no vcool or anything similar. But it is very odd that the switch
would go crazy too!

Using 100mbit switched network.

Not that I am aware of.. Running only one 8 port switch. Works good
with the 2.4.x kernels, but not with 2.5.. very odd.

Some things you might want to look at:
Is the Linux box sending any traffic (look at the stats in ifconfig)?
Does a packet sniffer like http://www.ethereal.com/ give any clues as to the
type of traffic on the network?
Does the same thing occur if you run less processes, e.g. boot into run level
1 or 3?
Are there any processes consuming an unreasonable amount of CPU time on the
Linux box?
Is there a process which is being restarted many times a second, so top or ps
shows a radiply increasing PID?
It could be some network-aware process which has got stuck in a tight loop
sending requests to your windows box, e.g. a DHCP client.
I mention the DHCP client specifically because they sometimes get upset if you
don't enable some specific kernel networking options like CONFIG_PACKET or
CONFIG_FILTER & WinRoute might be acting as the DHCP server.

nope, nothing like that. Running just a bare minimum...

Yes, you might be right. WinRoute is running as DCHP for the network,
and the problems do start as soon as Linux tries to lease an IP...

If you are using DHCP, it is critical that every machine have a correctly
set clock (see also: xntpd) Otherwise, the client may see the lease expire
before it requested it. (what happens in such a case varies with the software
and version.)

Yes, but everything works very good with 2.4.x kernels (all I have
tested so far). So the problems comes with 2.5.64.. And, there is not
much network traffic either when this happens...
