Junien, That is good feedback. I also received another request to backport this to 3.13 SO I'll be providing the hotfixed kernel in the same PPA soon (tomorrow morning most likely).
Attaching the 3.13 patches (just for reference since the SRU process requires me to send all those patches to kernel-team mailing list). Lets see if things continue good. If, by any chance, you are able to test this 3.13 kernel - maybe in another server - please provide me feedback also.

This clears up when the queue gets cleared, eg : block nbdX: queue cleared trusty hosts with kernel version 3.19.0-30-generic.
