Thanks, I'll take a look at that. .. Great! Email me directly (or CC: me) if/when you'd like some more testing. Another thing that could be a factor here, is that neither method (acpiphp or pciehp) seems "automatic". The user has to know to load one or the other module, or at least manually add them to /etc/modules. This could account for some reports of the mechanism failing. Shouldn't one or the other module be loaded automatically somehow when a system has hotpluggable slots? Probably a chicken-and-egg issue, I suppose, or something for a distro to fuss over. Cheers
