System is a PIII UP 2.4.5-pre1, NFS client, options from /proc/mounts:
arezzo:/usr/src/dolphin /usr/src/dolphin nfs rw,nodev,v3,rsize=32768,wsize=32768,hard,udp,nolock,addr=arezzo 0 0
Lately my "arpwatch" running on this 2.4.5-pre1 machine started to log
May 15 15:55:18 espoo arpwatch: 0:60:97:ba:b4:f5 sent bad hardware format 0x4500
hostname and Ethernet address correspond with the 2.4.5-pre1 machine itself.
To see what's really on the wire I ran "tcpdump -e -s 1500 -p -i eth0 arp"
on a separate machine with 2.4.0 and caught this:

A second run with an additional "-w file" option caught another bunch of
these. "strings -a file" showed (both good and bad packets):

Now this is strange. Everything marked with "=>" can be found in a temporary
file made by VIM on NFS on this 2.4.5-pre1 machine. To be more precise, I was
working on a file named "c_flow.c" and noticed a delay of a few seconds while
VIM was writing the ".c_flow.c.swp" file (guess). At the same time "arpwatch"
complained and I terminated the tcpdump to see what has been logged so far.
The ".c_flow.c.swp" file starts with a magic header "b0VIM 5.7".

Got the image of 3 interesting packets by letting a modified tcpdump dump
the entire packet buffer in arp_print().
Original tcpdump output:

The last 1304 bytes of 1.bin and 2.bin are identical to the first 1304 bytes
of the .swp file made by VIM.

As the subject already says, reproduced in 2.4.5-pre2.

To recap:
The machine is an NFSv3 client. The header of outgoing NFS UDP/IP packets
is sometimes corrupted, such that network sniffers on unrelated systems
report bogus ARP packets. AFAIK there is no data corruption on the
file level because the request is no longer recognized by the NFS
server. The symptom is also recorded in /var/log/messages on the client:
May 18 20:24:21 espoo kernel: nfs: server xxx not responding, still trying
May 18 20:24:21 espoo kernel: nfs: server xxx OK
In userland a short stall is experienced by the program which caused the
NFS traffic.
At most the first 196 bytes of a packet are corrupted (maybe some link
layer header must be added -- I'm not sure). In one incident the file
data of what was most likely an NFSv3 WRITE request was not altered but
a lot of the packaging was (not investigated any further but see earlier
mails). The bogus ARP packet contained the first 1304 bytes of a VIM swap
file just made by VIM, completely intact including the magic header "b0VIM".
A sniffer on the system itself is able to see the modified outgoing packets.
This problem is present in at least the following kernels:
2.4.0
2.4.2
2.4.4
2.4.5-pre1
2.4.5-pre2
This kernel configuration makes the difference:

It is probably possible to reduce the differences but I thought
this is interesting enough to mail it already. A second precondition
_might_ be the simple presence of the following iptables entry:
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
0 0 DROP udp -- ppp+ any anywhere anywhere udp dpt:route
The NIC might be a third precondition. Speed is 10Mbps. For the curious here
are all the bootmessages:
