Tried https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1.20/ - less
corruption and now the splash screen starts but as soon as splash
transitions to the X display we get an immediate hang.
I believe the 5.0.0 crash occurs before the splash screen starts, so
it's really early in the boot process.
Tried the same on an HP Mini 210-1000, Atom N450 and it works fine, so
this is a H/W specific issue.

One other data point, booting the upgraded machine to the 4.15 kernel
