Hi Michal, The patchset looks good to me. I didn’t find any issues during the testing. I have one concern regarding dmesg output. Do you think this messaging is valid if possible node is not yet present? Or is it only the issue for virtual machines? Node XX uninitialized by the platform. Please report with boot dmesg. Initmem setup node XX [mem 0x0000000000000000-0x0000000000000000] Thanks, —Alexey
