It looks like this is a vendor kernel and not an upstream kernel, yes?
 Assuming that is the case I would suggest you contact your distro for
help/debugging/support; we simply don't know enough about your kernel
(what patches are included, how was it built/configured/etc.) to
comment with any certainty.

Linux Kernels based on v3.10.0 are extremely old from an upstream
perspective, with a number of fixes and changes to the audit subsystem
since v3.10.0 was released.  If you see the same problem on a modern
upstream kernel please let us know, we'll be happy to help.
