- I can boot in non-xen ubuntu with the same kernel that doesn't work as dom0.
- Since I found reports of "decoding failed" issues due to the change to lz4 compression in 19.10, I tried changing back to gzip compression in /etc/initramfs-tools/initramfs.conf (and running update-initramfs -u), and this didn't help.
I should add two comments:
