Unfortunately, I have no idea.
Since there is no reason to stop at iinfo.c:62, I must check your
environment again. But your kernel is plain and no symbol conflict with
unionfs.

this trace is strange. But you might disable CONFIG_FRAME_POINTER. If so
that may be reasonable.
If your GCC is version 4, try version 3.
And I suggest you to enable CONFIG_DEBUG_KERNEL, CONFIG_DEBUG_SLAB,
CONFIG_FRAME_POINTER, and CONFIG_DEBUG_STACKOVERFLOW.
