Booted the 4.8.0-36-generic kernel with maxcpus=0 parameter and verified
all NVMe drives were initialized.

[Bug 1651602] Re: NVMe driver regression for non-smp/1-cpu systems

[John Donnelly]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
yakkety' to 'verification-done-yakkety'. If the problem still exists,
change the tag 'verification-needed-yakkety' to 'verification-failed-
yakkety'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Verified on physical box also, using maxcpus=0, with 4.4.0-58 nvme drive
fails to initialize, with 4.4.0-59 nvme initializes.

[Bug 1651602] Re: NVMe driver regression for non-smp/1-cpu systems

[Scott Moser]

To verify this is fixed, I have done the following.
For good measure, I've also successfully booted the above
with additional parameter '-smp cpus=2'.  That verifies that there is no
obvious regression on SMP system.

$ 
img_url="http://cloud-images.ubuntu.com/daily/server/xenial/current/xenial-server-cloudimg-amd64-disk1.img;
$ wget "${img_url}" -O disk.img

# patch the image to have a root passwd and disable cloud-init for simplicity.
$ sudo mount-image-callback disk.img -- chroot _MOUNTPOINT_ sh -exc '
touch /etc/cloud/cloud-init.disabled
echo "root:root" | chpasswd'

# attached 'get-kernels' enables proposed, installs linux-virtual into disk.img
# and copies kernels out to out.d
$ ./get-kernels disk.img linux-virtual out.d 
$ for i in out.d/*info; do echo == $i ==; cat $i; done
