--- Comment #12 from Roger Whittaker ---
I did a kexec reboot and then:
echo "module xhci_pci +mfp" > /sys/kernel/debug/dynamic_debug/control
echo "module xhci_hcd +mfp" > /sys/kernel/debug/dynamic_debug/control
rmmod xhci_pci
rmmod xhci_hcd
rmmod xhci_pci_renesas
modprobe xhci_pci
modprobe xhci_hcd
modprobe xhci_pci_renesas
echo "module xhci_pci +mfp" > /sys/kernel/debug/dynamic_debug/control
echo "module xhci_hcd +mfp" > /sys/kernel/debug/dynamic_debug/control
The relevant dmesg extract is:
