Well, I went ahead and downloaded the 3.18.4 source, copied my current config, ran make menuconfig, and enabled that option. Then I ran make rpm, which gave me a RPM that I installed and was able to boot from. However, while I do see the ACPI PCI Hotplug driver loading in the DMESG, I still don't see any indication of the thunderbolt controller or the drive I plugged in. Is there any chance I'm just being stupid here? That things ARE working, but are identified differently than I am expecting, so I don't see them? ----------------------------------------------- Israel Brewster Systems Analyst II Ravn Alaska 5245 Airport Industrial Rd Fairbanks, AK 99709 (907) 450-7293 ----------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
