I can confirm similar issues on AMD Threadripper. The issues went away on Ubuntu 17.10 by adding "pci_aspm=off" to grub, but are re-introduced by upgrading to 18.04. Strangely, the error now occurs in both 4.13 and 4.15 kernels.
One solution I found is to set PCIe to 2.0 instead of the default 3.0 in BIOS (but this comes at a slight performance cost). Do we know if this will be assigned / solved soon?
