Не загружается XEN. Invalid opcode ip in busybox [SOLVED]

Прошу помощи в следующей проблеме.
Ранее XEN ставился без проблем, а сейчас не могу загрузить ядро XEN.
Вылетает ошибка:

mount [1052] trap invalid opcode ip:45309f sp:7fff2d94de00 error:0 in busybox

line 34: can't create /proc/sys/kernel/printk: noexistent directory
can't open 'proc cmdline': No such file or directory

failed to mount /sys!

/init: line 251: can't create /proc/sys/kernel/hotplug: Noexistent directory

Теперь что и как у меня собрано:

Ранее на этом же сервере стоял XEN и работал.
Система с ядром не XEN отлично загружается и работает.
Уже все перегуглип, перепробовал.
Ничего не помогает.
Прошу помощи.
