Prior to that I had been instructed via the same bug report on Ubuntu Launchpad to update to the newest kernel to see if that would fix the issue. I'm now running 3.19.0-031900rc5-generic #201501180935 SMP Sun Jan 18 09:36:49 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux I've been asked on the Ubuntu bug report to do a 'kernel bisection' which I'm in the process of reading up on how to do this.
