What is your theory if the ISO size is valid? ?? And a k3b bug, but still dependent on the Linux kernel version? Why does it work fine with Linux < 2.6.24? I have never before had problems with verifying/reading ISO images from CDs/DVDs. I burn them in DAO (SAO) mode. With the same and other similarly reliable hardware I have never had to play with padding to work around run-out sectors at the end. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
