As yet another victim of this bug on bullseye/stable, I built grub2
package with this proposed patch, and I confirm the patched
grub2 2.06-3~deb11u1 packages fix the bug on a Xen server we
upgraded from 11.4 to 11.5 yesterday, where all PV/PVH domains
didn't start after reboot. Both hypervisor reboot (with autostart
domUs) and starting individual domU are all fine with the patched
grub2 packages.
I also vote for raising severity of this bug to "critical". Current
Debian 11.5 grub-xen-host package breaks all Xen PV/PVH domain boot
attemps.
