Comment 111 for bug 1774950

As I have describe above (#92), suspend did not work since kernel 3.16.57/3.17 on my Acer ES-512. A guy on ubuntuforum had found out that the problem disappeared when xHCI (external USB3.O controller) was turned off in the BIOS. The suspend problem also disappeared on my wife's laptop (another Acer Aspire).

Someone that is knowledgable about suspend, USB3.0 and changes after kernel 3.17 is perhaps able to figure out how to fix this bug.
