#59792 — Bug#885570: linux-image-4.9.0-4-amd64: display breakage with Intel HD Graphics 5500

Package: linux-image-4.9.0-4-amd64
Version: 4.9.65-3+deb9u1
Severity: critical

Recently, I've been having problems using my Lenovo X1 Carbon notebook 
(type 20BS, I think it's known as 3rd gen X1 Carbon).

By using the keyboard, or (especially) touchpad, I am getting really bad 
rendering artifacts (or flickering, not sure what the correct term is) 
on both the internal and external displays, and the latter sometimes 
even disappears for a second or so. Disconnecting the external display 
would sometimes prolong the "usable" period, but eventually the machine 
would become completely unusable anyway.

I had experienced different versions of "unusable": in some cases, the 
PC would freeze completely, and in other cases the laptop display would 
go berserk.

I ruled out this being a hardware issue, because booting an older kernel 
(linux-image-4.9.0-3-amd64 version 4.9.30-2+deb9u5) actually gets rid of 
the problem. I was also not able to reproduce it after booting from 
Ubuntu 17.10 Live USB.

Looking at apt history, I only see two upgrades to 
linux-image-4.9.0-4-amd64 this December: from 4.9.51-1 to 4.9.65-3 on 
11th and from 4.9.65-3 to 4.9.65-3+deb9u1 on 27th, thus my guess is that 
this regression happened somewhere inbetween 4.9.51-1 and 4.9.65-3 (the 
second upgrade was just yesterday, but I'm pretty sure the issue had 
already manifested before that). Looking at the Debian changelog, it 
seems there was a bunch of drm/i915 changes in 4.9.65-1, so maybe these 
changes cause the problem?

I'm using X.org and Cinnamon environment, but I was easily able to 
reproduce the same issue with Gnome and Wayland.

[Multipart message — attachments visible in raw view] — view raw

I also have reproduced this flicker which leads to a total freeze on my
Lenovo T450 running Stretch with Intel HD Graphics 5500.  It was
immediately noticed when rebooting and using the linux-image-4.9.0-4-amd
kernel.  Once I booted back into the previous kernel (4.9.0-3-amd) the
problem went away.  I also have a dell laptop that has Intel Graphics HD
520 that I upgraded to the 4.9.0-4-amd kernel and the problem does not
seem to affect it.  Looks like it might be some incompatibility between
the 4.9.0-4 kernel and the intel 5500 graphics?

Thanks

Dave

#59908 — Bug#885570: linux-image-4.9.0-5-amd64

Hi,

Same problem with linux-image-4.9.0-5-amd64.

The bad thing is: now we have the choice between being protected against 
meltdown and have terrible artifacts, or go back to linux-image-4.9.0-3-amd64, 
but being vulnerable to meltdown.

Pierre.

Thanks, I'm merging the bugs. I'm currently working on 4.9.75 but I'll
investigate reverting this or identify a more proper fix when it's done.

Hi Pierre,

Adding command line param as described here
https://01.org/comment/2855#comment-2855 worked for me. Still get
occasional flickering with switching windows/keystrokes but no crash.

Solution allows meltdown cover and usable machine.

Regards

Daniel

Thank you. Would enabling that repo/branch and testing help at all with
this?

My confusion is that https://packages.debian.org/stretch/linux-image-amd64
and https://packages.debian.org/stretch/linux-image-4.9.0-5-amd64 did not
match up. I wonder if this is a mistake. I will go back and re-read the
pages.

I updated to the stretch-proposed-updates version and am very happy thus
far. Sorry for the noise and thank you for the fix.
