I just found out that this behavior occures when the XHCI pre-boot mode
is enabled in the BIOS. Disabling it solve the issue.

If you plug the usb mouse in and boot with the nosplash noquiet options,
do you see the kernel text boot messages or does it go straight to the
desktop?

Without the usb mouse plugged in, before issuing the boot command, can
you run:
set debug=all
Then see if there is any additional output after the boot command?

It gives me many malloc lines but, I also have those in between:
Token 288 text [boot]
arglist
Token 259 text []
cmdline
token 0 text []
and the last one is:
append command
followed by:
script.c:50: malloc 0xbcebf1c0

Sorry, I forgot to mention you also need to remove the vt_handoff
option, so it should just be the uuid, ro, noquiet, nosplash.

No change in the behavior and still, simply having a usb mouse in one of
the usb port let it boot.

Can you try goingn to the grub command line and retyping the initrd and
linux command lines the menu normally executes, followed by the boot
command?
You can press E to edit the menu and see the commands, and C to get to
the command line for manual entry.

Done, after the boot command, it freeze right away. Just so you be sure
I done the right thing, here is what I have input (with and without
quiet splash):
$linux /boot/vmlinuz-3.5.0-17-generic
root=UUID=28584366-874d-4e68-aa27-eca80e966f40 ro quiet splash $vt_handoff
$initrd
So the initrd and kernel commands work, but after the boot command it is
just hung, with no further output? Can you try adding the nosplash and
noquiet command line options to the linux line?

Confirmed the bug in person.
Looks to me like it's not even getting to load the kernel, I tried
changing the parameters in grub to see kernel messages on the screen,
but it reacts the same way -- just getting a Loading initial memory
disk message from the command list in grub, and nothing else.
Setting priority to Medium; my best guess at importance for this bug. I
expect it's very much hardware-dependent; the system is an Asus Zenbook
of some sort.
Christian, can you please add the details about your laptop? Maybe add
the output of 'sudo lshw' or something, in case it can be useful.

It will freeze after Loading initial memory disk (or something like
this, this is a translation from french) and stay on the purple screen.
If I put the usb key in (no matter what is on it) after that line, it
gonna read on the usb key then, keep on it's boot procedure.
