Nothing obvious to linux-raid I'd say. It sounds like you have a hardware problem that either causes memory corruption which is then written out to disk, or the RAID controller you are using is defective and corrupts the data during parity calculations or something like that. It could also be a driver problem. You can try searching the linux-kernel or linux-scsi mailing list archives to see if you find any similar reports. Good luck!
