Ho messo su il kenel vanilla (odio i kernel patchati) e con tutte le altre distro provate masterizzavo senza problemi.
Se vi puo' essere utile posto anche il partizionamento:
/dev/hda6 / in xfs 18gb
/dev/hda7 /boot ext3 100mb
/dev/hda8 swap 1gb

Ragazzi ho risolto.
E' bastato andare in Desktop->Preferenze->Unita' e supporti removibile e disabilare la voce "Montare le unita' rimovibili quando montate a caldo" e tutto funge benissimo.
