Comment 4 for bug 1913470

I'm wondering now if *perhaps* kernel or kexec is involved. I don't reboot directly to the overlay kernel, I use:

`kexec --initrd=/boot/initrd.img-$(uname -r) --command-line="$(cat /proc/cmdline`) overlayroot=tmpfs" /boot/vmlinuz-$(uname -r) -l`

And we are on a custom 5.4 kernel (it's the nature of our HVs that we don't run the Ubuntu kernel). Can you try with kexec instead of overlayroot.conf config?

And can you tell me what kernel is in your VM?

The last part is this is baremetal, but I don't think that should matter.
