Can you try running each command in the menu entry manually to see
where the freeze actually happens? If the freeze happens after the
"initrd /path/to/initrd" command then it's almost certainly a bug in
grub. If the freeze happens after "boot" (every menu entry has an
implied "boot" command at the end) then it's more likely a firmware
bug or a bug somewhere in the kernel preventing a framebuffer from
successfully being created by / handed off to the kernel. No
framebuffer = no kernel output and apparent freeze. Sometimes the
"noefi" kernel parameter can work around problems between [U]EFI
firmware and the linux kernel.
