is this bare metal, or a VM ?
Is your dmesg-screenshot from same system? It mentions FOUR USB devices connected.
bare metal,
What device are you trying to boot from? USB thumb drive? Internal HDD? External HDD? If it's external then try to connect to another USB port.
Boot from the SAS hard drive of the built-in H310 array card
My guess is that it's missing a driver for the chipset of that card. Try SATA or USB.
