I therefore can only conclude that PVH grub doesn't like kernels

Can you boot the decompressed kernel on bare metal or in an HVM
domain using grub?
Oh that's interesting. The decompressed kernel doesn't boot bare
metal either (same message).
The decompressed kernel is generated like this:
# extract-vmlinux /boot/vmlinuz-5.4.0-52-generic >
/boot/vmlinuz-5.4.0-52-generic-decompressed
The decompressed kernel does boot when presented to the hypervisor
directly, i.e. no grub, directly listed in guest config file.
I don't have an HVM test setup right now so am unable to test that,
but I suppose we can assume it will fail as the problem is in the
standard grub loading functions.
So, is this a bug? Grub should be able to boot uncompressed kernels,
shouldn't it?
