Package: xen-hypervisor-4.4-amd64
Version: 4.4.1-9+deb8u3

Debian 8.2 installed on a supermicro H8SGL Board, AMD 6128 with 4x4GB
ECC RAM.

When booting the plain kernel (stock Jessie 3.16 or backport 4.1 or
4.3), both memory controllers (mc0 and mc1) appear under
/sys/devices/system/edac/mc with two csrow* each as expected. Same
happens, when booted with Xen 4.1.4-3+deb7u1.

When booted with Xen 4.4.1, only mc1 with two RAM modules is visible,
although all 16GB RAM is available in the OS (xl info).
