Thanks. I'll look into trying this on a test VM and let you know the outcome.
Do I just download these "mainline" kernel files using wget :- linux-image-4.2.0-*generic*rc4201507271733_i386.deb and corresponding linux-headers-* ? and then follow instructions at https://wiki.ubuntu.com/KernelMainlineBuilds to install ? The affected VMs are headless web servers, running on VMware. wiki.ubuntu.com/KernelMainlineBuilds says I need to uninstall "select proprietary or out-of-tree modules" Would this mean I need to uninstall VMware Tools on the chosen VM first ? It seems to put modules into the kernel with depmod.
