Public bug reported:
This bug is a follow on from a previously fixed bug.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184
The nature of this bug is identical to the previously reported bug, however it
also affects 256GB drives as well.
The wording at the start is a bit confusing, as it states that the 256GB drive
already has a quirk added. Following the trail back a little, however, shows
that a fix for high power drain was introduced, which then caused the NVMe
controller lockups and system hangs.
I am running Ubuntu 16.04 with HWE kernel [4.8.x, yakkety] on a Dell XPS15 9550
with a Samsung 256GB NVMe SSD.
This bug commenced with the kernel linux (4.8.0-47.50) yakkety, with the
specific change found at
