Can you try with kernel parameter 'acpi=noirq' or 'irqpoll'?
I made a typo when passing the irqpoll parameter to the kernel. In
kernel 2.6.20.4 with the irqpoll parameter passewd to kernel the SATA
disk works:

Nice isn't it? I'm happy.
Me happy too.
In the 2.6.21-rc5 version this hasn't worked (the typo was here too,
copy, paste & destroy :P). Here's is the output of dmesg:
That's weird. So, with irqpoll, 2.6.21-rc5 doesn't work while 2.6.20.4
does? I looked through the changelog but nothing looks suspicious at
the first glance.
Can you try 'pci=nomsi'? At first, I though you weren't using MSI. You
apparently are.
