Hi Andreas, I'm facing same issue on a 3.0.X kernel. I've tried to merge some patches to support SDIO irq on 3.0 kernel but without success. Interrupts are triggered and CPU load is greatly improved but performance is not here (1 Mbps up, 3 Mbps down) Did you actually get a working "SDIO irq" patch on a recent kernel or did you finally use 2.6.32 one ?
