The newest available version of linux-image-generic according to apt-cache showpkg is 3.13.0.100.108. (I'm running 3.13.0.98 right now.) Maybe 3.13.100 has the fix to this bug, but I'll have to figure out what's keeping back linux-kernel-image from being updated.What's really puzzling though is that I should have kernle 4.4.x, since I'm running Ubuntu 14.04.5, according to the Ubuntu Wiki: https://wiki.ubuntu.com/Kernel/Support#A14.04.x_Ubuntu_Kerne... It's strange that my Kubuntu installation is frozen on 3.13.x.
