But that is not so severe based on the fact that there are no substantial data loss with those checksum errors. I used to get some some kernel panics under "too may check sum erros" and after disabling "sha512|skeun|edonr" checksum algorithm, the server has been running well for more than two weeks. It looks like "sha512|skeun|edonr" checksum algorithm still has some glitches.
