Additional info:

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
Comment 2 Dan Hollis 2005-02-03 18:00:25 EST
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.
Comment 3 D. Hugh Redelmeier 2005-03-14 14:52:46 EST
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.
Comment 4 Dan Hollis 2005-03-14 17:28:43 EST
-pad does not work. have not tried padsize.
Comment 5 Dan Hollis 2005-05-23 16:00:24 EDT
this appears to be because of the readahead in kernel.

someone suggested using raw devices to bypass readahead.
Comment 6 Dave Jones 2005-07-15 13:59:21 EDT
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.
Comment 7 Dave Jones 2005-10-02 20:28:05 EDT
This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
