Perfect. I'm unable to install OS on Supermicro H8DG6-F motherboard. Problem is allocation of memory to PCIe bus. There are 2 external cards: Myricom
10GbE dual port NIC and 3x Fusion-MPT SAS-2 boards. System worked perfectly under 2.6 kernel but nothing from 3.16 to 4.6 work. In worst case nothing
works, in best case 2 of 3 storage boards and 10GbE NIC works, but still there are those messages:
