I would like to report that I also have the same boot problem on a 
RHEL6.4 box with the crypto patch. My workaround is to force kernel 
build to have the crc_t10dif code built-in by changing the config file:

4889c4889
< CONFIG_CRYPTO_CRCT10DIF=m
---
> CONFIG_CRYPTO_CRCT10DIF=y
5002c5002
< CONFIG_CRC_T10DIF=m
---
> CONFIG_CRC_T10DIF=y

This solved the boot problem without any additional patch.  Do you think 
you should consider changing the configuration default to "y" instead of 
"m" or doesn't allow the "m" option at all?

Thanks!
