I've experienced the same with coreboot+EDK2(MrChromeBox) on a Thinkpad T400. If you still have trouble booting the platform, I've somehow managed to bypass it by rebuilding with 64bit mode enabled.

Updated by Arthur Heymans 9 months ago 

    config SMM_MODULE_STACK_SIZE
        hex
        default 0x800 if ARCH_RAMSTAGE_X86_64
        default 0x400

So just bumping this to always use 0x800 might be a solution
