I'll give that a test as well. My existing config is using Path=pci-0000:05:00.0 and that works, but when I try to match on Property=Path=pci-0000:05:00.0 Driver=oak,it doesn't. this doesn't make sense to me. I was hoping that I can have specific matches for hte PCI addresses and Drivers that I can use to match both sets of configuration with and without the hotplug board. Henti
