While looking over the stack dump one of our engineers noticed the text "Not tainted 3.2.0-4-amd64 #1 Debian 3.2.41-2 ".  Could this mean I'm looking over the wrong source?  It would make me feel better as I'm not seeing anything as is. :)

Indeed, this is not 3.9.

The version of ixgbe in this Debian kernel has bql support backported,
but is otherwise the same as in 3.2.41.  I assume that this bug has
been fixed some time between 3.2 and 3.9, but no-one requested that
the fix be included in stable branches.  Please can you identify the
fix?

Ben.
