It looks like you have header CRCs disabled ("ms crc header = false" in ceph.conf). This is not supported by the kernel client -- only data CRCs can be disabled.
Note that in order for it to be effective, you need to disable it both on the OSD and the kernel client sides: "ms crc data = false" in ceph.conf and rbd map -o nocrc.
