We do have a test system, and the only significant difference from
production is the kernel.
Test are para-virt VMs with "regular" kernels, production are real
machines with hardened kernels (grsec+pax).
I got prod onto a regular kernel and nothing in nearly an hour.
8.3.5 has worked forever and a day on this type of setup.
