La próxima vez usaré "pstree" y haber si aclara esta paranoia de la xterm
gigantesca.

Efectívamente, el disco duro empieza a moverse y no para... le pone a uno
mal de los nervios.

A tope lo que se dice a tope no está optimizado pero poco a poco lo intento
descargar de cosas "compiladas dentro". Actualmente la imagen es bzImage y tiene un
tamaño de 492631. Mando pegado mi ".config" del núcleo por si alguien tiene
el suficiente tiempo, ganas y moral de mirar si hay algo que no deberiera
estar, también pongo la salida de "dmesg" para que se vea como arranca mi
máquina.

Lo haré.
