I have the same issue on 3 Laptops (2 HP nc6230 and 1 Asus, all 32bit systems), only solution so far is to revert to Linux 4.15.0-47. I could not find any useful hint in any of the logs.
One strange thing is that only every second boot fails. After hard power-off a hanging boot the next boot works fine one time, but the next one again hangs.
I could not even get a text console with Ctrl-Alt-F1 in case it hangs.
