When a host that supports PKRU initiates a guest that lacks PKRU support, the

On most machines you can hide the problem by using these kernel
Seems it's fairly easy to make a working solution in initramfs-tools
alone, but there's a compromise. If I only include tiny/simple

all the current drm

I think the delay I'm seeing is a feature of Plymouth, not a bug:
"ignoring since we only handle SimpleDRM devices after timeout"
As much as I dislike it perpetuating bug 1869655, this feature does
prevent bug 2054769 from reoccurring.
But this raises the question: is it worth putting i915,
