This bug was introduced in v3.10.6.  It has been fixed in mainline 3.12-rc2 by commit a0c516cbf.  This commit was requested in upstream stable and is queued to be included in upstream stable 3.11.2.

== Test Case ==

A test kernel was built with this patch and tested by the original bug reporter.  An ISO was also built with the test kernel and shown to resolve the bug.
