Comment # 11 on bug 1190411 from Oliver Neukum

We have to make sure that the Renesas 64 bit quirk is applied properly. Could
you rerun the test with dynamic debugging for the xhci_hcd module enabled with

echo "module xhci_pci +mfp" > /sys/kernel/debug/dynamic_debug/control
echo "module xhci_hcd +mfp" > /sys/kernel/debug/dynamic_debug/control
