When testing, it works fine without the (request_bufflen % 256) workaround as needed in libata. ide-scsi filters out (pc->request_transfer % 1024) and use PIO, so the pdc202xx ATAPI DMA problem is avoid. Both ide-cd and ide-scsi won't hit the ATAPI DMA problem on pdc202xx_new. Signed-off-by: Albert Lee Signed-off-by: Bartlomiej Zolnierkiewicz --- Reading git-diff-tree failed
