This is a kernel error. The ceph userspace code is extremely unlikely to be responsible. Regardless, this needs to be debugged by whoever supports this kernel as a first step. A google search for "page dumped because: PAGE_FLAGS_CHECK_AT_PREP flag set" shows similar bugs which may give some guidance.
