Public bug reported: == Comment: #0 - Haren Myneni <hb...@us.ibm.com> - 2015-09-19 20:35:29 == ---Problem Description--- Hardware team reported some rare data corruption during uncompression for nx842 co-processor. It might provide user with invalid data after uncompression. So the fix is add CRC support - means Linux adds CRC flag before calling the nx842 so that CRC will be added and checked during compression and uncompression calls.
