Testpatch for fixing null pointer deref at failed xhci init
This patch should fix the Oops, but xhci might still fail to load.
Can you test if it helps?

Created attachment 147061 [details] dmesg output captured from crashed system I had a crash with Kernel Oops for the first time with Kernel 3.16. The system only bootet up to the initrd shell as the root device was not mounted successfully. A reset of the machine helped to get the kernel boot successfully without any errors. Today (upgraded to 3.16.1 in the meantime) I had the same problem, again. This time I've captured the dmesg output which is attached to this bug report. For me it seems like the xhci has some serious problems and causes the boot process to stop. Again, a reset of the machine helped to get the system up without any further errors.
