Медленная загрузка после обновления, проблемы XHCI_HCD

Я обновил до 16.04 на днях, и мое время загрузки стало очень медленным. У меня двойная загрузка на Macbook Pro с использованием rEFInd. Судя по выводу dmesg, я думаю, что это проблема с драйвером xhci_hcd. Я видел несколько мест, где люди сталкивались с такой же проблемой, но я сталкивался с любыми решениями.

Вот некоторая соответствующая информация:
