[coreboot] SPD CRC failed

SPD is some data saved on the memory module, available to the
processor to read to find out memory properies. These data are
protected by a check code (CRC) which allows the CPU to verify that it
read the data correctly. Apparently this check is failing in your
case.

Some likely reasons could be  a noisy i2c interface (used to read SPD)
or someone writing the SPD storage on memory module(s) and
corrupteding it.
