I also have successful reports with this driver, so problem is not
common. So I don't think it is reasonable to back-out it now. As soon as
you are the only complaining now, it is only you who can debug the
issue. So could you be so kind to provide more info? Even without
keyboard you should be able to get verbose boot messages and full panic
