Thunderbolt controller unresponsive after firmware update (26) on 9360 0x82A

[baybal]

Situation:

lspci not showing the thunderbolt controller, forcing power does not work. I managed to make it to show in lspci after cold boot after 4 second shutdown button press and having a USB device connected to it at boot. But it is still unresponsive even after forcing power to on.

dmesg |grep -i tbt

Any updates?

Finally, got the trick: you have to echo 1> /sys/bus/pci/rescan if you have PCI powersave enabled
