Could be that your DDR init code somehow generates an exception that is 
triggered once trap_init() is called. This is also know to happen in the 
common denali_data_eye code. See here:

#if defined(CONFIG_DDR_DATA_EYE)
                /*
                 * Running denali_core_search_data_eye() when ECC is enabled
                 * causes non-ECC machine checks.  This clears them.
                 */
                print_mcsr();
                mtspr(SPRN_MCSR, mfspr(SPRN_MCSR));
                print_mcsr();
#endif

I suggest you analyse this and the Denali registers for any source/status of a 
generated exception.

Cheers,
Stefan
