the (long)table_header->size, I think it is not same with coreboot.
Now I can build a payload with "--with-platform=multiboot" that can boot my machine, not the "--with-platform=coreboot".

I have read the source code about the mmap of grub and of corebootV4,
I found that the size of their table header struct are not same, and I
think ,in the file "mmap.c" of grub2,on the 53rd line, the offset of
the first table item may be error.

In my copy 53rd line is completely empty. Could you detail the error?

BRs,
Rock.

      I received you reply this monday, then my office PC had a
    problem ,can not power on, so I write you late.
    I have tried to run "dd", but got "Reading a error address".

    I would also need another memory location for full diagnostics:
    sudo dd if=/dev/mem of=tables bs=1 count=65536 skip=2146422784
    Looking at the code, the only way it can hang AFAICT should be fixed by
    attached patch (mostly guessing)

    1. I have tried the "--with-platform=multiboot" option, but when
    booting it show me:
    /*********************/
    Welcome to GRUB!
    out of memory
    Aborted.
    /*********************/
    2. The /dev/mem you need , how can I get it? I want it should be from
    the "/" , then I must enter the ubuntu.
    So I use the grub1.98 as coreboot payload and boot my ubuntu11.04.
    But when I copy the /dev/mem to a log file with "sudo",
    I was told “You can not do it!” : (

    So I checked out the changelog from 2348 to 2349 :


    Ironically I did it because i386-coreboot didn't work in my tests.
    Could
    you send me the first 128K of /dev/mem ? Meanwhile you can try
    i386-multiboot port.
