I see, a different issue then.  It's just weird to see similar issues 
popping up now after allterm the time sata_sil24 has been around.

Clarence, it seems it could be that what's broken is irq routing not 
sata_sil24 itself  I dunno anything about irq routing on PPC440SPE but I 
bet there are kernel parameters to adjust them including irqpoll.  Do 
those have any effect?
