OK, good, that's expected. In $subject you mention EFI. Is this old system really EFI based? Anyway, I finally got around to downloading: http://cdimage.debian.org/debian-cd/current/amd64/bt-cd/debian-7.7.0-amd64-CD-1.iso.torrent and booted with: qemu-system-i386 -M isapc -cdrom debian-7.7.0-amd64-CD-1.iso and I get a hang after selecting "Install" from the bootloader menu. They I downloaded this: http://d-i.debian.org/daily-images/amd64/20141130-00:21/netboot/mini.iso and booted with: qemu-system-i386 -M isapc -cdrom mini.iso and it reported as expected: This kernel requires an x86-64 CPU, but only detected an i486 CPU. Unable to boot - please use a kernel appropriate for your CPU. Aha! If I remove the "quiet" from the kernel command line with debian-7.7.0-amd64-CD-1.iso (press TAB on the entry instead of ENTER, edit, then hit ENTER) then I see the message with Wheezy too, so the bug seems to be that quiet is suppressing a useful error message as well as the usual noise. I can't see a commit in Linux which obviously fixes it, but there are lots in that range even just over arch/x86/boot and some of them are rather non-obvious after a quick peek, there's some stuff refactoring debug and quiet mode output handling, I'd bet it was in that somewhere. If not then I think mystery is resolved and Jessie is fixed, so I won't plan to spend any longer investigating.
