I'm getting the same error. I upgraded from Feisty to Gutsy. I had one problem in the upgrade and had to abort. I completed the upgrade in a terminal with these commands...
sudo apt-get --configure -a sudo apt-get update sudo apt-get dist-upgrade Th upgraded completed successfully. When I rebooted there was a long delay at the splash screen then this... Check root= bootarg cat /proc/cmdline or missing modules,devices: cat /proc/modules ls /dev ALERT! /dev/disk/by-uuid/(boot disk uuid) does not exist. Dropping to a shell. Then I get the Busy Box banner and prompt (initramfs) I have used blkid to verify the uuid is correct. I've edited /boot/grub/menu.lst and /etc/fstab to use drive path (/dev/hdb5 & /dev/sdb5) instead of uuid. I also modified /etc/initramfs-tools/modules and added these lines (from a post at Launchpad)... # added for support of older, standard hdx drives piix ide_generic ide_cd ide_disk # black-list bad driver ata_piix # prevent unnecessary modules from loading (optional) blacklist ata_generic blacklist libata blacklist scsi_mod And then ran... sudo initramfs-tools -u 2.6.22-14-generic to rebuild the init image. I have also removed and re-installed the kernel image (while booted into my Feisty kernel) but that, too did not work. So far nothing has worked. I still boot to a busy box prompt with a message indicating my hard drives can't be found. I am able to boot to my Feisty kernel without any problems. This seems to be an ongoing bug. Is there any hope of a fix? I really DO NOT want to have to reformat my PC to solve this upgrade problem.
