Quite possibly your board has bad SDRAM routing.  Enabling debug disables
the cache, and the decompressor without debug seems to be an excellent
test for identifying marginal SDRAM signal quality.

Basically, if you get a CRC error on decompression, it means that the
image was corrupted somehow.  Experience shows that's not the fault of
the code but tends to be hardware weaknesses.
