Sure, what about
"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."

Thanks,

Alberto
