Booting L4Linux/Fiasco with root=/dev/hda

[FERANDELLE Pascal]

I try to boot L4Linux (kernel 2.6.17) on Fiasco, on a PC which has already RedHat Enterprise Linux 4.0 installed, with root=/dev/hda3.

The Linux kernel begins to boot, but after the messages :
...
kjournald starting. Commit interval 5 seconds
EXT3 FS on hda3, internal journal
EXT3-fs: mounted filesystem with ordered data mode
VFS: Mounted root (ext3 filesystem)
Warning: unable to open an initial console

Nothing else appears on the screen, but I can see the station is still alive, because the disk led is still highlightening frequently, then everything stops, and I have the message "Restarting system" on the screen.
Nothing else happens ...

Any idea, first for the opening problem of the console, and then, about what can happen after that, would be nice !!!
Thanks

Pascal
