Description of Problem: After upgrading RH 6.1 box to 7.1, system won't complete boot. Error message is "failed to mount root fs on 8:x" How Reproducible: Upgrade Dell PowerEdge 2400 with factory-installed RH 6.1 to RH 7.1 using RH 7.1 install CD Steps to Reproduce: 1. Use 7.1 upgrade, choose all defaults 2. Reboot after install complete 3. Boot won't complete. root fs is /dev/sda6, and that's what /etc/lilo.conf says it is, but because the RH install loads the SCSI controller as a module rather than part of the kernel we never load the root fs Actual Results: Kernel panic upon failure to mount root fs Expected Results: Normal boot Additional Information: System is Dell PowerEdge 2400 ServerSet LE motherboard 2 533-MHz CPUs 256 Mbytes RAM Adaptec Perc 2-Si RAID controller Adaptec AIC 7880 SCSI controller Factory installed RH 6.1
Can you boot into the system with rescue mode and send us your /etc/modules.conf? We install an initial ramdisk (initrd.img) on SCSI systems that should avoid this problem.
