That's interesting.  The RX bug that I fixed earlier would usually
manifest itself under exactly these conditions.  Alas you're running
a fixed kernel.

Can you take a tcpdump of the TCP sessions involving those IPs and
then show me the sections that occur when those messages are triggered?

The question is always what you want to be off and what to leave on.
After all, you can turn off all printk's to the console through /proc.
If you also tell klogd to ignore them then you won't see anything at
all (unless you run dmesg).
