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.
