Interesting, you don't have any hugepage information, it's probably
disabled in the kernel. Can you apply th attached patch and check that
the XML output only contains a single "page_type" line and that it
looks valid ? It should be something like
<page_type size="4096" count="256834"/>
If so, then rerun make check again.
Looks like you have some unexpected hugepage information. Not sure it's
the cause of the XML problem, but we need to debug this too. Can you
send the .tar.bz2 and .output file that hwloc-gather-topology.sh
In the meantime, I need to change this test so as to show the
difference between the XML exports when this make check test fails.
