Red Hat Bugzilla – Bug 139386
CD test failure at 99%

Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I wasted 3 cd-rs to burn FC3 CD1 and still the media test fails at
99%, so as for all other 3 CDs. Crap happens when burning CDs, but 6
times the same.. All went OK with FC2.
Does the testing suceed if you start the installer with "linux cddma=off" ? If
so then this a dup of bug 106685
i get exactly the same thing with cddma=off
it stops at 99% and switching consoles it gives sector read errors
that looks like its trying to read off the end of the CD.
This might be related to bug 151088.
The workaround is to burn the CD with extra padding. cdrecord has a
-pad option that should do it (I haven't tried it). Perhaps 15
sectors is not enough -- you might need to use padsize=33s.
What I has worked for me is appending a a couple of megabytes of zero
to the .iso file before burning it with cdrecord. I think that the
padsize=33s approach is cleaner.
-pad does not work. have not tried padsize.
this appears to be because of the readahead in kernel.
someone suggested using raw devices to bypass readahead.
