Package: grub-xen-host
Version: 2.06-3
Followup-For: Bug #1017944
X-Debbugs-Cc: pkg-xen-de...@lists.alioth.debian.org
I can confirm this issue happening on an up-to-date Bookworm system with
a 5.19.6 kernel and also with a 5.18.16 one.
I'll leave adjusting the severity up to the GRUB maintainers, but I
think a good case can be made for 'grave' or 'critical' as it breaks an
important group of Xen VM types (unrelated software).
