I tried unplugging network > cable and compiling out the fec driver. i did the last weeks some tests and it seems that the "problem" persists. I boot my system like descripted below and I have an error rate of about 5%. If I reboot my system, start start the program and then unplug the networkcable the error rate is much lower. This is my configuration: Board MPC5200 Lite5200 Evaluation board (not version b) U-Boot 1.2.0-gfdd1d6dc (Mar 6 2007 - 12:52:10) Kernel is loaded via tftp and the complete filesystem is mounted via NFS. Crosscompile/basesystem is ELDK 4.1. You can see exactly what I did under: http://wiki.idefix.fechner.net/index.php/IceCube Kernel is Linux-2.6.21-mpc52xx-g7e5e3d6f-d with some patches from the mailinglist (I2C patches and powermanagement patches you submitted on the ML) and Xenomai support. I attach my kernel config and a small program with which i read my Maxim 6633 temperatur sensor you can order it as sample on the maxim website. Maybe something is wrong with the program or it is a problem with the MPC5200 which is fixed with the 5200b.
