"Can you try 4.20-rc2 and boot with kernel parameter `pcie_aspm=off`?"
I suggest first trying 4.20-rcX and seeing if it freezes at least once. If it does, try booting for a few days with pcie_aspm=off in the kernel parameters. Post back results.
I can't do that right now, because I'm not currently running Ubuntu 18.10.
