I think this comment was from Satish about ide=nodma. Why is that necessary? I've encountered the mediacheck failures similarly for the first time ever. If the drive operates normally, why do we need nodma in order to check only disk2 and disk3 of the CD set? I'm not intending this as disrespectful to anyone; I'm truly curious about it. Out of the four install images, all four pass the MD5 checksum test, and two out of four pass the mediacheck. On my CD writer, cdrecord reports that the buffer was always adequately filled and burnfree protection was never needed. So assuming the integrity of the media is OK (seems to be, since cdrecord reports no errors and the CD is readable), I'd suspect a problem with the original ISO image. Whether you use DMA or not on your drive doesn't seem to have any bearing on things....else other I/O would have trouble too. Am I missing something? Erik > >>
