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.

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?
