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.
