Медленная начальная загрузка после обновления, проблем XHCI_HCD

Я обновил к 16,04 на днях, и мое время начальной загрузки стало действительно медленным. Я - двойная загрузка на использовании MacBook Pro, повторно находят. Оценка от вывода dmesg, я думаю, что это - проблема с xhci_hcd драйвером. Я видел несколько мест, где у людей есть эта та же проблема, но я сталкиваюсь с любыми разрешениями все же.

Вот некоторая соответствующая информация:
