Preámbulo

Por alguna extraña razón el firmware de la tarjeta de red inalámbrica solamente funciona con el kernel GENERIC_LAPTOP de la serie de kernels que el proyecto de NetBSD provee.

Con este kernel solamente puedo usar un sólo CPU ya que el procesador de mi laptop es un Intel Duo, además de que por alguna razón, la conexión inalámbrica tiende a “desfallecer” de forma aleatoria dejando sólo el siguiente mensaje como despedida:

[$] dmesg | grep wpi
wpi0: Device timeout.

y la única forma de revivirla es reiniciar el equipo.

Un día fastidiando a la gente del canal de NetBSD en el FreeNode me puse a platicar con un usuario de nombre ficovh acerca de este problema, él me recomendo que compilara un kernel usando el código reciente ya sea de la rama estable o de la experimental.

Viendo cómo me había ido con el kernel de Linux decidí dejarlo para luego pero, lamentablemente, el problema aún persistía.

Ya entrando en más confianza con el usuario, luego de las clásicas preguntas que de dónde era, cuánto tiempo tenía usando NetBSD y todo eso, resulta que es mexicano el chavo, que él fue el iniciador del Wiki de NetBSD de México y que además es mi paisano.

Con tal que, animado por el usuario y por las pláticas que había tenido con mi maestro pro bono, Malditron, decidí agarrar la vida por los cuernos.

Después de varios intentos he aquí el relato de mi experiencia.

Procedimiento

Primero configuramos el CVS:

[#] vi ~/.cvsrc

# recommended CVS configuration file from the pkgsrc guide
checkout -P
update -dP
release -d
diff -upN
cvs -q -z3
rdiff -u

Ahora descargamos la rama STABLE:

[#] cd /usr

[#] cvs -q chekout -r netbsd-4 -P src

Nos situamos en donde están los kernels:

[#] cd /usr/src/sys/arch/i386/conf

Creamos nuestro kernel

[#] cp GENERIC.MP wanda

El contenido del kernel GENERIC_LAPTOP lo copiamos a nuestro kernel:

[#] cat GENERIC_LAPTOP >> wanda

Configuramos nuestro kernel:

[#] config wanda

y vamos a obtener los siguientes errores:

*** Stop.

Lo que sigue es lo aburrido del proceso y es comentar todas esas líneas.

Volvemos a configurar el kernel y vemos con satisfacción que ahora si funcionó:

[#] config wanda
Build directory is ../compile/wanda
Don't forget to run "make depend"

Creamos las dependencias y compilamos:

[#] cd ../compile/wanda

[#] make depend && make

Despues de un rato esto es lo que vamos a obtener:

[#] ls -lh netbsd
-rwxr-xr-x 1 root wheel 10622276 May 1 02:12 netbsd

Reemplazamos el viejo kernel:

[#] mv /netbsd /netbsd.old

y situamos nuestro nuevo kernel:

[#] mv netbsd /

Reiniciamos y esperamos.

Probamos si ya podemos usar los dos CPUs:
