Instale y tengo un error feo con Ubuntu 9.04 server

[santa]

Buenas chicos recién termine de instalar un Ubuntu 9.04 server en un AMD Phenome 9950 con dos discos en espejo y 8gb de ram, si una maquinita simpática como verán, pero cuando arranca y pasa grub me tira el siguiente mensaje:


Starting up ...

y luego arranca con la carga de todo como es de costumbre.

Me podrían comentar que les parece estos mensajes y si es conveniente dejar Ubuntu y poner Debian Lenny? bueno muchas gracias a todos por su tiempo, saludos
