    [PATCH] libata: let ATA_FLAG_PIO_POLLING use polling pio for
ATA_PROT_NODATA
    
    Even if ATA_FLAG_PIO_POLLING is set, libata uses irq pio for the
ATA_PROT_NODATA protocol.
    This patch let ATA_FLAG_PIO_POLLING use polling pio for the
ATA_PROT_NODATA protocol.

Now, why it dies after that, I don't know, it's one flag being added.

I guess I could try the latest kernel with that removed and see what
happens?

Cheers,
Eamonn
