#12885: XHCI page fault under skylake

Description changed by kallisti5:

Old description:

_ZN4XHCIC2EP8pci_infoP5Stack() ->  XHCI::XHCI(pci_info*, Stack*)
_ZN4XHCI5AddToEP5Stack ()     -> XHCI::AddTo(Stack*)
_ZN5StackC1Ev ()   -> Stack::Stack()

New description:

 This issue generally occurs when booting from a USB 3 flash drive.

 {{{
 _ZN4XHCIC2EP8pci_infoP5Stack() -> XHCI::XHCI(pci_info*, Stack*)
 _ZN4XHCI5AddToEP5Stack ()      -> XHCI::AddTo(Stack*)
 _ZN5StackC1Ev ()               -> Stack::Stack()
 }}}

 This line seems to be a core issue in syslog:
 {{{
 usb xhci -1: using message signaled interrupts
 usb xhci -1: stating XHCI host controller
 usb hub 2: hub supports more ports than we do (18 vs. 16)
 usb xhci -1: successfully started the controller
 }}}
