I tried with the irqpoll parameter (used in the right way) and the sata

the SATA disk is detected properly.
This is for kernel version 2.6.17, I must be falling asleep.
Matias, are you still there? If so, can you please test the attached
patch and see whether it fixes your problem - ie. boots okay without
'pci=nomsi'?

Okey, I'll try the patch and let you know how it goes. I'm sorry for not
having test it but I'm been studing a lot these last few days. Tonight
I'll test it. Thanks!
