Package: shim-unsigned Version: 15.8-1 Severity: important The shim binaries are being built with relaxed file alignment requirements. This makes some of UEFI implementations reject shim binaries. For example Lenovo Miix 630 boots grubaa64.efi, but rejects shimaa64.efi. Most likely this is because of the header differences. Compare:
objdump -p shimaa64.efi: ... BaseOfCode 000000000001e000 ImageBase 0000000000000000 SectionAlignment 00001000 FileAlignment 00000200 ... objdump -p grubaa64.efi: ... AddressOfEntryPoint 0000000000001000 BaseOfCode 0000000000001000 ImageBase 0000000000000000 SectionAlignment 00001000 FileAlignment 00001000 ...
