Hi,

This was fixed by our qdio developer recently, but the fix is not yet
upstream. However, I doubt that this is related to the hugetlbfs problem.

I was able to reproduce the "Bad page state", with the current libhugetlbfs
development snapshot and your patch for s390. It only happened on machines
with software large page emulation, but we certainly have a problem there.
Thanks for reporting this bug and adding s390 support to libhugetlbfs, I
will look into this problem.

Thanks,
Gerald
