Description of problem: I'm trying to install FC4 on a MPC clientpro system (with a SATA root disk) and receive the following messages during the initrd stage: RAMDISK: Couldn't find valid ramdisk image starting at 0 VFS: cannot open root device "<NULL>" or unknown-block (8,3) Then kernel panic. I've seen similar issues with FC2 when upgrading a kernel and not recreating the initrd with these options: --preload=sd_mod --preload=scsi_mod --with=ata_piix However, I'm not sure how to rebuild the install cd with an updated initrd to try this. Version-Release number of selected component (if applicable): How reproducible: You may not be able to reproduce this where you are depending on the type of systems you have. The FC4 install cd works fine on a gateway system we have also with a SATA root disk. It may be BIOS/motherboard rev dependant.
Indeed. Most likely the strange workaround in Bug 159026 will allow you to boot your system. An announcement explaining what happened is forthcoming. *** This bug has been marked as a duplicate of 159026 ***
