I just installed 2006.0, 1st boot appeared to be going smooth then error "The root block device is unspecified or not detected - Please specify a device to boot, or "shell" for a shell.
FSTAB:
Code:

/dev/hda3                   none      swap         sw                                 0 0
/dev/hda4                   /         reiserfs        notail,noatime                 0 1

none                           /proc     proc          defaults                          0 0
none                           /dev/shm  tmpfs     nodev,nosuid,noexec       0 0

/dev/cdroms/cdrom0    /mnt/cdrom    auto      noauto,user                0 0

yaboot.conf:
Code:

boot=/dev/hda2
device=hd:
delay=5
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
image=/boot/kernel-genkernel-ppc-2.6.15-gentoo-r1
  label=Linux
  root=/dev/ram0   
  partition=4
  append="real_root=/dev/hda4 init=/linuxrc"
  initrd=/boot/initramfs-genkernel-ppc-2.6.15-gentoo-r1
  initrd-size=8192
  read-only


Any help would be appreciated

You probably left support out of your kernel for one of the below things:

1. IDE Chipset Support (CONFIG_BLK_DEV_IDE_PMAC)
2. Mac partition support (CONFIG_MAC_PARTITION)
3. Support for your root filesystem (CONFIG_REISERFS)

They are enabled, but generally as modules. Failure to include the reiserfs module in your initrd could cause the problem you are seeing.
