Hi,

It might look as if the XHCI is receiving no interrupts, which is not an 
XHCI fault. When removing the timestamps and diffing I see changes like:

intpin=c, irq=11

->

kernel: intpin=c, irq=255


And one ACPI change:

kernel: ACPI: RSDP 0x7ad8e014 00024 (v02 APPLE )

vs

kernel: ACPI: RSDP 0xfe020 00024 (v02 APPLE )
