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.
