So the communication with the controller works (dmesg dumps a list of
ports etc.)? Do you get plug events ("resetting error on port ...")?
You could try to play around with tb_plug_events_active, if you want
to experiment. I can also take another look at what OS X does once I
get back to my workstation (when I worked on this part falcon ridge
was not jet released, so maybe they do things differently now).

I have obtained ACPI dumps from a late 2013 MBP and from a MacPro
(both are falcon ridge devices) and these contain a few firmware
changes. For example SXIO, SXIL and SXLV are gone so the shutdown
quirk will fail. With some luck that means that the shutdown quirk is
no longer required for falcon ridge hardware.
Can you try the following on your MacPro?
- Boot with your ACPI patch, nothing plugged in, no thunderbolt driver
- Verify that NHI is present (lspci)
- Plug in a tb device
- Suspend and resume
- Check that the NHI is still responding using lspci -vv
On my cactus ridge MBP the device id of the NHI now reads 0xffff (the
device is gone, Linux just doesn't know). If the NHI is still alive
then they fixed their hardware :)
