Problema con DMA, en el nuevo kernel 2.6.12.3
Hola, bueno os explico, estoy recompilando el kernel 2.6.12.3 y me
funciona todo a la perfeccion, es mas ahora estoy escribiendo desde
ese kernel.
La historia es que en el arranque tengo un problema de DMA cosa que no
ocurre con el kernel que tengo instalado desde el cd de netinst de
sarge (el kernel 2.6.8-2).
Os pego lo que es el arranque de los dos kernels y el log al intentar
activar el dma en el kernel 12. Ya he buscado en google, y la gente
que tiene ese problema con el comando hdparm -d 1 /dev/hda lo
soluciona, pero en mi caso no es asi. Otra cosa es que no se que me
puede faltar o que he puesto mal, en el kernel que he recompilado,
porque he probado muchas opciones y ninguna termina de funcionar.
Muchas gracias y aqui van los logs

Ohh decir, que esos paquetes que dice "cargando modulos" yo los tengo
puestos dentro del kernel, no se si eso podria llegar a influir.
Muchas gracias
