More accurately it is "program exception," which is also triggered by
illegal opcode.  Did the tool chain change between the two RTEMS versions
in question?  If the newer version got compiled with an opcode which
doesn't exist in the 405 core by some mistake it could trigger the same
exception.
FP exception seems more likely, but just wanted to throw that out there.
Might be worth taking a look at the disassembly.
