md5sum -c MD5SUM
I've already indicated this once. After successful MD5SUM check - boot with 'linux ide=nodma' and then do the MediaCheck.)
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?

Check the fedora-test-list for discussions regarding the mediacheck failure. Padding the discs with at least 150 kb was suggested, loading the ide-scsi or using the 2.4 kernel was suggested. I guess there is some breakage which happened with the change to the 2.6 kernel.
I'm glad that adding ide=nodma to the installer before a mediacheck works to verify the discs successfully. This also probably helps ensure more reliable installs with systems that show the mediacheck false result during verifying.
I feared a mass explosion of coasters because of this problem and no reference to the problem within the release notes. For those reading this list, the coaster collection is probably lower.
For installers not on the list and attempting an install, the mirrors, reburning discs multiple times and giving up on the release might be at higher levels.
