FU exceptions should carry a cause (IC)
As per the ISA we need a cause and executing a tabort r9 in libc for example causes a EXCP_FU exception, we don't wire up the IC (cause) when we post the exception. The cause is required for the kernel to do the right thing. The fix applies only to 64 bit ppc targets.
