Duplicate of 137217 ?

I get media check failures using FC3 for these disks burned with
"uptodate" RH9

FC3-i386-disc2.iso
FC3-i386-disc3.iso

MD5SUM's for all 5 discs (1-4 + rescue) agree with values posted on
mirror site.

Reburned discs 2 and 3 at slower speed with better media in RH9

cdrecord  -v speed=12 dev=1,0,0 ~robert/FC3-i386-disc2.iso

and obtained errors again at the very end of the media check process
as indicated by the progress bar. My RH9 system burns CD extremely
reliably (~1 coaster/80) so I will ignore the failures and try to
install anyways.




Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Burn MD5SUM checked FC3 ISO images on patched RH 9 system using   
   cdrecord -v speed=12 dev=1,0,0 ~robert/FC3-i386-disc2.iso

2. Insert ISO 1 in cd tray and boot system from ISO 1.

3. Run media check on 1,2,3,4 and rescue.
   
    

Actual Results:  ISO 2,3 fail media check at the very end of media
check as indicated by the progress bar.

Expected Results:  Media check to pass for all FC3 ISO images.

This is caused by a kernel bug.
Comment 2 Need Real Name 2004-12-05 18:33:47 EST
The same thing is happening to me, only with the x86_64 ISOs.
md5sum reports correct checksums on all my ISO images before I burn
them, but the FC3 installer rejects all four of the CDs.
I burned them multiple times at various speeds down to 4x on
48x-certified media, but it made no difference.

Curiously, 3 out of 4 of the i386 FC3 ISOs I burned on the
same burners passed the test. (Disc 2 failed.)

Is it safe to use these CDs to install?
Comment 3 Normand Robert 2004-12-05 23:18:22 EST
I was able to install without any problems.
Comment 4 O.R.Senthil Kumaran 2005-01-14 15:08:11 EST
Using linux ide=nodma during install will resolve this and will not
give this Media Check failure issue (with CD2 and CD3 isos)

I faced the same problem with: _NEC CD-RW NR-9100A  Drive.
which could not work properly with dma during Install.

_NEC CD-RW NR-9100A  should be added to the list of nodma blacklist.
(Is there any Bug# which is collecting the devices which has problems
with DMA)


[ors@h1c661s ~]$ cat /proc/ide/hdc/model
_NEC CD-RW NR-9100A

[ors@h1c661s ~]$ dmesg | grep CD
hdc: _NEC CD-RW NR-9100A, ATAPI CD/DVD-ROM drive
hdc: ATAPI 40X CD-ROM CD-R/RW drive, 2048kB Cache
Uniform CD-ROM driver Revision: 3.20
[ors@h1c661s ~]$

I had same problem on a Sony laptop w/ Toshiba DVD-RW SD-R6012.
Setting ide=nodma resulted in passing the media check. 
Comment 6 Joe Dupre 2005-07-14 01:28:54 EDT
I should have noted above that all of my FC4 CD images were failing until I 
added the ide=nodma switch.
Comment 7 Dave Jones 2005-07-15 15:54:10 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 8 Normand Robert 2005-07-15 19:36:52 EDT
Does this mean that the iso distribution itself has been updated? 
Comment 9 Dave Jones 2005-07-15 19:51:02 EDT
no, the ISOs never get respun.  Sometimes a new boot.iso is created, but not always.

For this bug, after an installation, and update to the new kernel, running the
media check from the anaconda-runtime package should now work.

I know its a little backwards to do the check /after/ you've installed, but this
should also mean that FC5 and onwards should have this fixed. Hopefully.
