    Subject[PATCH 4.14 020/148] usb: xhci: apply XHCI_SUSPEND_DELAY to AMD XHCI controller 1022:145c
    Date
    From: Alberto Mattea <alberto@mattea.info>

    commit 16263abc12d09871156a1c8650fb651f0e552f5e upstream.

    This controller timeouts during suspend (S3) with
    [ 240.521724] xhci_hcd 0000:30:00.3: WARN: xHC save state timeout
    [ 240.521729] xhci_hcd 0000:30:00.3: ERROR mismatched command completion event
    thus preventing the system from entering S3.
    Moreover it remains in an undefined state where some connected devices stop
    working until a reboot.
    Apply the XHCI_SUSPEND_DELAY quirk to make it suspend properly.
