Hi Jan,
Any chance you can get the contents of /sys/kernel/mm/hugepages before and after the first run of libhugetlbfs testsuite on Power? Perhaps a script like:
cd /sys/kernel/mm/hugepages for f in hugepages-*/*; do n=`cat $f`; echo -e "$n\t$f"; done
Just want to make sure the numbers look as they should.
