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? -- tejun
