It looks as the fdc driver is stuck in a loop and the init process never
gets pass this stage.

To see if that is the culprit, find the floppy.ko and rename it to say
floppy.ko.bak. Then recreate the initramfs.

The more worrying is the irqs firring. Try to use the 'irqpoll'
parameter as it suggests.
