Hi Nikolay, must have missed it.  I looked quickly, but didn't find
it.  Since it's such an older kernel release, it might be best if you
upgrade to the latest version and try to re-create the lock if at all
possible.  

What kind of workload are you running on there?  And if you have more
details on the hardware, that might help as well.
