Hi Bjorn,
	We will try to work out a patch for this issue, won't silently ignore it.
We also found another issue related to ARI. The steps to reproduce the bug is:
1) Boot with a ARI-capable device connected to ARI-capable port, so ARI will be enabled.
2) Hot-remove the ARI-capable device.
3) Hot-add another non-ARI-capable multifunction device into the same slot.
4) Now only the function 0 of the hot-added device could be enumerated.

	I think Yijing is going to work on the above two issues.
	Thanks!
	Gerry
