Ok, that worked. Backing out all the changes made it shutdown
again.

Since this shouldn't by the right way to fix this problem, what
else can I do Andrew?

The BIG Problem is: This is an embedded machine, so I cannot
attach all the funny debug tools. The most thing I can do is
printk and evtl. ikdb. I have only 16MB flash disk on this
machine and it is full already :-(
