Hi Denis,
thank you very much, works fine !
But my diff to the original xhcp-pci.c of Kernel 3.14.4 is:
$ diff xhci-pci.c-original xhci-pci.c-changed
137,138d136
<
< xhci->quirks |= XHCI_SPURIOUS_REBOOT;
139a138,141
> if (pdev->vendor == PCI_VENDOR_ID_INTEL &&
> pdev->device == PCI_DEVICE_ID_INTEL_LYNXPOINT_LP_XHCI) {
> xhci->quirks |= XHCI_SPURIOUS_REBOOT;
> }
just fyi
regards Wulf
