Comment 23 for bug 1880172

Last strange thing I've noticed :
in dmesg, I've got an error about irq not handled:

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.
