I tested on my nvme system with the boot param 'maxcpus=0' (i.e. UP mode), the boot fails with kernel 4.4.0-57, because the nvme drive fails enumeration, with the error from comment 2. With the 4.4.0-57 kernel including my nvme patch, and using boot param 'maxcpus=0', the boot succeeds. The patched kernel is at this ppa:
https://launchpad.net/~ddstreet/+archive/ubuntu/lp1651602

and the patch is here:
https://lists.ubuntu.com/archives/kernel-team/2016-December/081637.html

the patch fixes a bug introduced by my previous commit 96fce9e4025b ("NVMe: only setup MSIX once")
which is only currently included in Xenial, so this patch only needs to be applied to Xenial.
