Have a look at the changelogs:
https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.15.4 and
https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.15.5.
Looks like it could be a DRM issue. Which graphics hardware and driver
stack are you using?

Ran into a weird issue today. I upgraded a bunch of packages, including the kernel to v4.15.4-1 (from 4.15.3-1). But for some reason the system was un-bootable. The boot process would get part-way through, then the booting screen would suddenly start showing its text on a green background (rather than black) and it would freeze.
It took some jumping through hoops, but I was eventually able to boot to a chroot environment, upgrade to a newer kernel (v4.15.5-1) and suddenly the problem magically went away and my machine boots fine.
Anyone have any idea what might have happened here? I'm assuming it was a bad kernel build, but I'd like to know for sure. I didn't see any recent bugs under the "linux" kernel package that matched what I was seeing.
Thanks,
DR
