How did this config both crash and not build? i'm testing on multiple systems in parallel, each is running randconfig kernels. One 64-bit system found a build bug, the other one found a boot crash. This can happen if certain configs build fine (but crash), certain configs dont even build. Each system does a random walk of the config space. I've applied your two fixes and i'm re-testing.
