Yes, or dodgy connectors or other problems. The CRC itself is computed by the hardware each end so a BadCRC error really means the two ends disagree about the data.
That is *usually* a cable/electrical noise problem. It can be power and it can occasionally show up if the software misprograms the timing so the two ends are a bit out of sync.
