TCPv4 Checksum errors

I have reported this problem after I was unable to download a
particular file (mentioned URL earlier).

Upon request from Alan Cox I have already sent the tcpdump.

Since I use a monolithic kernel VJ compression can't be the problem
(isn't available).

Machine load could have an impact - I am running the rc5-64 and
mprime client so my machine load is almost about 2. Will try this...
