--- Comment #41 from Andre Robatino andre@bwh.harvard.edu 2009-01-03 19:51:21 EDT --- The readahead bug should only affect reading the last few dozen KB of the disc image. You also need to be careful not to use dd to attempt to read off more than the actual size of the ISO. The rawread script at
http://www.troubleshooters.com/linux/coasterless.htm
reads off the correct amount automatically. It's very handy; I make it executable and put it in ~/bin so it's always available in my path.
Using "ide=nodma" may or may not work, depending on your hardware (it usually didn't work for me). Doing the burning as recommended in the link above seems to be the only foolproof way to avoid the readahead bug.
