This appears to be hardware/firmware related (specifically a problem with the motherboard). There is some sort of IRQ conflict when one of the PCIe slots is being used. The IRQ conflict was there in 14.04 as well, but didn't seem to cause any problems. Moving one of the NVME devices to a different PCIe slot solved the IRQ conflict and all of the resulting issues.

These servers have been running 14.04 without issues. When trying to install 16.04 only one NVME device was visible and the installer would freeze up. I booted a live USB (ubuntu-mate 16.04) and found the syslog was getting spammed with an infinite loop of kernel oops messages. I attached a trimmed version of that log. Sometimes the sysem would hit a kernel panic and freeze, but I don't have a setup to capture that currently.
