From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050921 Red Hat/1.7.12-1.1.3.2 Description of problem: I burned several FC4 ISOs (for installing on another machine) using cdrecord. The burning exhibited no errors, but the installation failed. I checked the disks using "mediacheck," and they failed. I asked on LinuxQuestions, and was told to use "dma=off" in the mediacheck, and that succeeded. I'm told that the installation will succeed the same way, though I haven't tried that yet. The exact command I used was: cdrecord -v -dev=ATA:1,0,0 -eject -data FC4-i386-disc3.iso I checked the sha1sums for the ISOs I burned and they were fine. Burning those same ISOs using a Mac OSX produced CDs that installed just fine. So it really seems to be a bug with CD record. You might argue that it's not a bug, since there is a workaround, but I've been using Redhat and Fedora for years without hearing about dma=off or understanding what it means, so it seems to me that the workaround is obscure enough that this counts as a bug. There is an "easy" workaround, so perhaps I've miscategorized the severity, but because the workaround is somewhat obscure, I've classed it as a bug. Version-Release number of selected component (if applicable): cdrecord-2.01.1-9.0.FC4.1 How reproducible: Always Steps to Reproduce: 1. Burn ISO using cdrecord -v -dev=ATA:1,0,0 -eject -data FC4-i386-disc3.iso 2. Boot from a working FC4, disk 1 3. type "linux mediacheck" at the prompt 4. test the burned CD. this will fail. 5. reboot from the same working FC4, disk 1 6. type "linux mediacheck dma=off" at the prompt 7. test the burned CD. this will succeed. Actual Results: disk failed the medicheck Expected Results: disk should pass the mediacheck Additional info:
please use "-dao" for burning
Also, because I think this is more an anaconda/mediacheck issue, which should use the isosize and not the number of bytes read from the device, I am reassigning this to component anaconda.
Again, with Fedora Core 5 media won't pass the mediacheck test here unless I give "ide=nodma". Tossed a few (presumably good...) CDs away... CDs were burned on a DVD writer under Fedora rawhide (almost Fedora 5).
This report targets the FC3 or FC4 products, which have now been EOL'd. Could you please check that it still applies to a current Fedora release, and either update the target product or close it ? Thanks.
With RHEL V5 x86-64 on an AMD based system I get mediacheck errors on discs 1 and 4 of the release. I confirmed the md5sums were correct on the iso file images and reburned disc 1 - still get errors reported. Tried mediacheck with dma=off; still get errors reported. tried mediacheck with ide=nodma and after initial progress get "Kernel alive" and "kernel direct mapping tables up to 260000000 @ 8000-13000" then system hangs. Will go ahead and try install with these discs as not sure what else to do. Think there is still an issue w/ mediacheck in V5.
Fedora Core 5 is no longer maintained. Can you reproduce this bug in Fedora 8?

This bug is open for a Fedora version that is no longer maintained and will not be fixed by Fedora. Therefore we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen thus bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
