Dear Brice, thank you for your answer. Neither upgrade of BIOS nor using the latest hwloc helped. Finaly we contacted AMD and they fixed a bug in kernel which coused problems with 12-core AMD processors. They should upstream the changes to kernel.org soon, so that all the distros (Centos,RHEL,SUSE etc.) can pick them up automatically as they create their respective next releases.

Anyway, this is a very common error on AMD 6200 and 6300 machines. See http://www.open-mpi.org/projects/hwloc/doc/v1.11.0/a00030.php#faq_os_ error (http://www.open-mpi.org/projects/hwloc/doc/v1.11.0/a00030.php#faq_os_error) Assuming you kernel isn't too old (CentOS7 should be fine), you should try to upgrade the BIOS.

I am using hwloc.x86_64 v1.7-3.el7, which is its latest version available in standard packages for CentOS 7. Is this something, what has been already encountered and fixed in newer versions of hwloc?
