Неудачная загрузка после установки

// Эта проблема решается вот уже 2 неделю

Имеем Gentoo amd64 2.6.34-r1

Установка строго по английскому хендбуку. При установке было собрано ядро с помощью genkernel, но вручную (genkernel --menuconfig all) была добавлена поддержка Ext4.
Был размаскирован и собран Grub2 (1.98) после чего установлен.

# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't 
# needed; notail increases performance of ReiserFS (at the expense of storage 
# efficiency).  It's safe to drop the noatime options if you want and to 
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.

# <fs>			<mountpoint>	<type>		<opts>		<dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for 
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
#  use almost no memory if not populated with files)
