I have a brand new install of Rocks Cluster OS 7.0 and I'm trying to test-install a few nodes. Everything in the system seems fine, but when I try to install a new node with insert-ethers, the PXE process fails saying that the initramfs is corrupted and then the node reboots, trying to be installed over and over.

The weird thing is that vmlinuz and initrd are downloaded fine, the system starts to boot, but when it has to uncompress the initramfs, it fails.

Nodes specs are here:

Motherboard: AsRock AB350 Pro 4
EFI Ver: P4.70
Processor: AMD Ryzen 3 2200G
RAM: DDR4 2400Mhz 16GB

I've tested the installation with some old hardware, and it works, so there must be an incompatibility between the kernel (?) and the specified hardware.

The uname -r output says: 3.10.0-693.5.2.el7.x86_64
