Brice, I just tried that but the output is the same. As Samuel pointed out, it looks like /proc/cpuinfo is totally bogus for this kernel. Comparing it with what it "should" be emitting (according to http://kbase.redhat.com/faq/docs/DOC-7715), it doesn't report more than one under "cpu cores", and core id is always 255!

Try setting HWLOC_LINUX_USE_CPUINFO=1 before running the old lstopo (without the x86 backend), it might be better.
