That isn't an upstream kernel configuration; it looks like includes suse
patches. But, yes, it does crash almost immediately if I build an upstream
kernel based on it and try to run that kernel in qemu. I did not try to
track it down further; after all, it might just be that the configuration
is inappropriate for use with qemu. But the configuration isn't really
what I had asked.
