A floating point trap could be one of several things, including

1) a device driver that specifies floating point numbers (the kernel is
   not allowed to use floating point).

2) a compiler mis-configured to use floating point registers for structure
   copy

3) A device or driver is scribling on memory

4) Your memory bus or controller is not configured correctly or your board
   is getting noise, corrupting memory.

1 and 2 can be eliminated by checking the instruction at NIP in your vmlinux,
possibly by objdump.   3 would tend to be unlikely at the low address but
not impossible.
