I got some problem with the XOR engine while creating the RAID array.

I doubt that you will get much (more) attention if you continue to spam
the list, also with people distributed around the world, expecting a
solid reply within less than 8 hours is at least a bit questionable,
don't you think so?

The parity data is getting corrupted and my system is not able to recognize 
it and some how we are getting the hard disk error.

I found the above issue is happening when I  enable  
CONFIG_RAID_ZERO_COPY=y in my Linux configuration.

Without this option everything is working fine.

I think (I'm only a user myself and no developer), without much more
extra information, it will be hard to help, i.e. more information what
kern.log/dmesg shows in both situations, /proc/mdstat output, mdadm
examine, ....
