    you are right, i misread the - cpu_gdt_table is aligned

    c02a39e0 D cpu_gdt_table

    so it must be something else that prevents booting on those boxes. Does
    the boot BIOS code perhaps assume a certain GDT layout? A certain size?
    Does it overwrite certain GDT entries perhaps?

    yes. Fortunately this makes no difference, the LDT and the default DS/CS
    are in a single cacheline still.
