[Intrepid] No monta disco USB

Sab Oct 25 11:00:09 BST 2008

Hola:

He instalado Intrepid beta hace unos 15 o 20 días y aparte de unos
"pequeños problemillas" corre de maravilla. Sin embargo hay un "pequeño
problemilla" que me tiene especialmente quemado.

Se trata de un disco USB Samsung de 250 GB que no me lo monta. He estado
esperando para ver si se solucionaba, pero al llegar ayer la RC y no
verlo solucionado lo expongo aquí (en launchpad hay varios errores, creo
que similares, reportados pero no se si alguno es el mismo, p.e. [1],
aunque es para Hardy)

En Hardy funciona perfectamente, así como en Debian Lenny.

Al conectarlo, el dmesg me devuelve lo siguiente:

:~$ dmesg
