Ondrej, would you please test this new series? Changed since v1: - PDMA transfer residual is calculated earlier. - End of DMA flag check is now polled (if there is any residual). Changed since v2: - Bail out of transfer loops when Gated IRQ gets asserted. - Make udelay conditional on board type. - Drop sg_tablesize patch due to performance regression. Changed since v3: - Add Ondrej's workaround for corrupt WRITE commands on DTC boards. - Reset the 53c400 logic after any short PDMA transfer. - Don't fail the transfer if the 53c400 logic got a reset.
