Re: Bug: unable to handle kernel NULL pointer dereference at 0000000000000020

[Francisco Magallanes Díaz <f.magallanes@live.com>]

No, no tengo otra versión de kernel que pueda usar, la versión 2.6.32-5-amd64 es la única que tengo. Las cabeceras si las pude instalar, cuando descargué el compat-wireless seguí los pasos de instalación indicados en la página http://linuxwireless.org/en/users/Download/stable/, descomprimí la descarga, me fui a la carpeta con los archivos descomprimidos y procedí a usar el comando "make", el error fue el siguiente:

Antes de reiniciar la lap y que tuviera estos problemas también instalé el paquete firmware-ralink 0.28+squeeze1.

Parece un bug en el kernel ¿tienes algún otro núcleo que puedas usar?
Incluso uno más antiguo?

¿puedes describir los pasos en los que te quedaste al instalar
compat-wireless? Si no pudiste instalar las cabeceras no pudiste
instalar compat-wireless y eso significaría que no hiciste nada :p

Saludos

Hola a todos!
Bueno, pues les platico el problema que tengo. Hace unos días traté de
instalar compat-wierless, sin embargo tuve que instalar el paquete de
linux-headers. Sin embargo no pude instalarlo correctamente, estaba
cansado y apagué la lap. Cuando la volví a prender tuve un problema,
cuando cargaba el ambiente gráfico (KDE), al momento que aparecía la
ventana para iniciar sesión tras unos segundos se trababa. Después la
reiniciaba y cuando estaba cargando se detenía mostrando esto:

Tras apagar la lap y volverla a prender, a veces carga el ambiente
gráfico pero se traba tras unos segundos y otras veces me aparece el
siguiente kernel panic:

He tratado de solucionarlo por mi cuenta pero no he tenido éxito.
De verdad agradecería su ayuda.
Supongo que esto es causado por el intento fallido de instalación del
compat-wireless o la instalación del paquete linux-headers pero no se
como solucionarlo.
Uso Debian Squeeze con la versión de kernel 2.6.32-5-amd64.
