Bug#616638: using the "linux" command twice in a row causes grub-efi-amd64 to hang

[Daniel Kahn Gillmor]

Package: grub-efi-amd64
Version: 1.99~rc1-3
Severity: normal

Booting grub-efi directly on a new macbook pro, i found that if i
accidentally did:

 linux (hd1,gpt2)/vmlinuz root=/dev/sda3 ro verbose
 linux (hd1,gpt2)/vmlinuz root=/dev/sda3 ro verbose

(that is, if i loaded the kernel twice) then grub would hang.

Other variants of grub (grub-pc and grub-ieee1275) don't seem to show
this behavior.

I also note that if my second command points to something that is not
a file, grub does *not* hang.
