Last strange thing I've noticed :
in dmesg, I've got an error about irq not handled:
[ 9.512884] irq 9: nobody cared (try booting with the "irqpoll" option)

If I try to reboot with "irqpoll" I don't have this error anymore, but
another about iwlwifi and a "kernel panic" dump (not sure it's called as
this), and wifi doesn't work anymore, but I don't get more touchpad.
