hwloc-gather-topology does not gather I/O devices unfortunately (we could gather OS devices, but we can't for PCI devices). What do you have under /sys/bus/pci/devices/<yourpcibusid> ? Do you see anything like hostX in there? What does in contain? Can you walk in there until you find a "block" child? I haven't tested on recent kernels lately, maybe something changed in the sysfs hierarchy, I am booting a 3.5 to check things. Brice
