I was able to reproduce this.  Pid #0 (swapper) ends up with a preempt
count of two and everything goes pear-shaped.

This appears to be because you haven't selected any chip drivers in IDE
config.  I selected PIIX and things started working better.

Just to double-check I took my usual .config, enable preemption, disabled
all IDE chip drivers and the same thing happened.  Over to Bart ;)


Your .config seems broken in other ways btw.  Suggest you do 

	cp arch/i386/defconfig .config

and start again.
