| |
We received several reports of systems rebooting and powering on after an attempted shutdown. Testing showed that setting XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT quirk allowed the system to shutdown as expected for Lynxpoint xHCI controllers. Set the qurik.

There was some discussion if this is actually needed across all chipsets or if it's just some revision. Not sure how to narrow that down. --- drivers/usb/host/xhci-pci.c | 1 + 1 file changed, 1 insertion(+)
