Title:
Using an NVMe drive causes huge power drain
I'm pretty sure this is not the first time a power-saving feature breaks
some subset of hardware. Why even add it in a bugfix update?
After applying the workaround from LP#1678184, I'm happy about the
somewhat improved battery life, but I'll never get back the several
hours it took to figure out

Title:
Using an NVMe drive causes huge power
Unfortunately, this fix breaks Dell XPS 9550 with Samsung PM951 drives.
I now get a hung system due to the Samsung controller getting reset.
Please see https://bugzilla.kernel.org/show_bug.cgi?id=195039 for a

The quirk detection is not complete, I fear

After some reasonable big time of use, I get (as far I noticed in user
interface or system journals) no errors and not any hang. I did not
notice any slowdown either.
Thanks a lot, my battery is smiling again.

@Dave,
For Zesty, it's already in the tree.
For Yakkety, I already sent patches to kernel-team ML.
For Xenial, I'd like to see if there's any regression after some real world
usages in Yakkety and Zesty - after all the patch author made a blacklist table
for a reason. If everything goes
@Kai-Heng have you been able to make any progress on this? I think Tim
is simply waiting on a git branch or git send-email submission to the
kernel-team mailing list.

I was wrong, you are right, it's not a clean cherry-pick.
I picked 7ac8b7abdb8d903c83fa15cfd952316e824fe6f3 from nvme tree (which
can be clean applied) instead of

@Tim, When I checked the backport it was not a clean cherry-pick. As
you mentioned earlier there was some prerequisite patches that git
pulled in. I did not continue investigating, but I guess there should
only be a few. Either way the patches seem nvme

I can confirm Kai-Heng's patched kernel (linux-

I've tested it now and it seems to work flawlessly.
Power usage is very similar to 4.11 kernel.
It would be great to see your patches in Zesty.

I can confirm Francois experience with my 950 pro. Although I saved one
or two watts. It's a bit hard to tell. However my PC states were
already reaching PC8 before this patch.

I know that my bugs seem to me more important than other people's bugs
because that's MY bugs :-) .
But *IMHO* this lack of NVMe power management (and consequently Skylake CPU low
power states usage) is critical since :
1) it voids a lot of power management efforts these last years in
Francois - I doubt if that is going to happen for 17.04. It appears that
single patch requires a substantial amount of infrastructure and
prerequisite patches.

Status:
Solved upstream with kernel 4.11 RC1 from Ubuntu kernel archive.
I'm back to 4.23 W instead of 8.26 W in same power conditions.
I reach PC8 power state (powertop) instead of PC3.
Hope the APST Andy's patch (I guess it's the key ?) will be backported
soon to Zesty's kernel.
