These logs show clearly that we are seeing interrupts which
should be disabled.
Could it be that we we have either the status or enable bits
mixed up? Unfortunately the publically available docs for GEN4
don't show the HOTPLUG_EN and HOTPLUG_STAT registers.

Daniel, could you please help me out here?

Thanks a lot!

Cheers,
	Egbert.
