Package: grub-efi-amd64 Version: 2.12-1 Severity: important Dear Maintainer,
Upgrading to GRUB 2.12 makes my system unbootable. It immediately breaks with the following error before giving me a chance to see any menu or get any better debug output. !!!! X64 Exception Type - 0D(#GP - General Protection) CPU Apic ID - 00000000 !!!!

Find image (No PDB) (ImageBase=000000005FDD8000, EntryPoint=000000005FDD9000) !!!! This is consistent across several similar machines, so I suspect a software regression rather than a hardware issue. FWIW the EFI BIOS is American Megatrends Version 2.20.1276 Core Version 5.14 I realize that this is not a lot to go on, but I would appreciate any hints on how to debug this issue.
