The system had not problems during the installation process. I have perform=

>How-To-Repeat:
Boot the system with a  Ricoh 5C476 PCI-CardBus bridge (rev. 0xa9) activate=
d.
(I have an Asus M2400Ne notebook, I tried to boot with GENERIC and
GENERIC_LAPTOP but the problem remains.
>Fix:
The only fix is to disable the bridge from BIOS. But it is obvious and not
useful...
