Ha ok, I still have to learn more :)

For the moment I reach to avoid any crash of 2.4 with pdc_console either I boot from graphics(0) or serial_1.
My patch works well (i can read from pdc kdb) for serial_1 but for graphics(0), I get well a login prompt from pdc
but unfortunately I don't yet reach to read from usb kbd.
But does it make sense to have pdc_console when we have an sti console?
(imho it have well sense for a serial and lan console. Please advise.)

Thanks again,
	Joel
