alpine-xen-3.18.0-x86_64.iso doesn't boot correctly in UEFI CSM
I am trying to install alpine Linux® on a hp EliteBook 620 g3. https://dl-cdn.alpinelinux.org/alpine/v3.17/releases/x86_64/alpine-xen-3.17.3-x86_64.iso boots fine in UEFI CSM but https://dl-cdn.alpinelinux.org/alpine/v3.18/releases/x86_64/alpine-xen-3.18.0-x86_64.iso does only show a blinking underline cursor.
Booting Xen via UEFI is broken on multiple Linux® distributions and FreeBSD. So this is a whole different issue that does not matter here.
