I have posted this against the kernel because I see that is where other problems reported against mediacheck have been posted. I am refering to issues 135795 and 150186 against RC3T3 and WS4 respectively. I do not know (nor do I care to waste the media to see) if using CDR's instead of CDRW's makes any difference. does the problem go away if you boot with ide=nodma ? Booting off CD (disc1) and entering "linux ide=nodma" and then doing the mediacheck, the check still fails. can you try disabling readahead on the cd device? eg: hdparm -a 0 /dev/cdrom I do not see any way of issuing "hdparm -a 0 /dev/cdrom" having booted from the install media. Alternatively, I do not see any way of running the media check once I have the OS installed. I did try "linux mediacheck nocddma", but it still fails. I have also performed a "readcd dev=/dev/cdrom f=disc1.iso" (on the same laptop with the same drive and the same disk that fails the mediacheck) and it has the same sha1sum that the SHA1SUM file says belongs to FC4-test2-i386-disc1.iso. I'm willing to try just about anything here... other suggestions? The mediacheck is working with the new FC4T3 i386 CD-RW's I have burned. Any idea what fixed it? Not sure. There are lots of IDE layer improvements in the kernel since test3. The installer folks also changed the way mediacheck works. It now checksums smaller segments instead of the one whole image. It might just be a change in the access patterns on the CD that have made the bug more difficult to reproduce. FC4T3 mediachecks seems to work for me now as well. FC3 and such were definitely broken. Mass update of -test bugs to update version to fc4. (Please retest on final release, and report results if you have not already done so). Thanks. mediacheck works on fc4 final release for me. |
