Package: grub-efi-amd64-bin Version: 2.04-2 Severity: normal Dear Maintainer,
after upgrading grub to 2.04-2, my vm's stopped booting in 64 bit uefi mode with the error below. When using tcg, the vm simply hangs. Both shortly after the "Welcome..." message. This might well be a bug in qemu, but it seems that grub itself is simply crashing. Booting in 32 bit uefi mode or bios mode works, and so does 64 bit uefi booting once grub is downgraded to the buster version of grub. Last log messages of OVMF before the crash: InstallProtocolInterface: 605DAB50-E046-4300-ABB6-3DD810DD8B23 7E2E8E90 FSOpen: Open '\EFI\BOOT\grubx64.efi' Success PixelBlueGreenRedReserved8BitPerColor KVM crash message: KVM internal error.
