Процесс загрузки.
Видно сгенерированное меню. Затем небольшой выхлоп ядра. Что происходит потом проще увидеть. Ждал достаточно долго но система не загружается.
Причина как оказалось в настройке фреймбуффера в ядре. Он у меня был на vga, vesa.

В общем значит так вышеописанную проблему, по совету бывалых, решил таким образом. Во первых пересобрал ядро на uvesafb с такими параметрами

Далее надо было поправить конфиг. В окончательном виде он у меня выглядит так

Ну и пока собственно все. Заработало отлично. С темами и прочим украшательством пока не игрался. Устраивает и так как есть. Да где именно прописать “video=uvesafb:1280x800-32,mtrr:3,ywrap raid=noautodetect boot_delay=0 ” чтобы оно добавлялось параметрами по умолчанию пока тоже не понял.
