But as you said, the memset(&dsp_core, 0, sizeof(dsp_core_t)) will 
overwrite the DSP program with NOP, so after DSP_Init is called at the 
end of the restore, there's no more valid program in the DSP :(

So, latest changes prevented the crash, but it was not correct, I will 
change it do not call DSP_Init after the snapshot is loaded.
