[Kernel-packages] [Bug 1608042] Re: 64-bit XUbuntu 16.04 "Xenial" hybrid graphics (Intel + AMD): AMDGPU crashes / freezes / hangs entire system

[Yuri Ribeiro Sucupira]

While the first good commit isn't applied downstream (in order to fix
previous kernel versions), I currently recommend using stable kernel
4.7.4, available at http://kernel.ubuntu.com/~kernel-
ppa/mainline/v4.7.4/

There are newer stable kernel versions available, but I haven't tested
them. I can confirm, though, that kernel 4.7.4 solves the "freezing"
issue. One running 64-bit Ubuntu Linux and interested in installing
kernel 4.7.4 must download these files:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux-
headers-4.7.4-040704_4.7.4-040704.201609150330_all.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux-
headers-4.7.4-040704-generic_4.7.4-040704.201609150330_amd64.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux-
image-4.7.4-040704-generic_4.7.4-040704.201609150330_amd64.deb

...then open a shell terminal window, "cd" into the folder where these 3
DEB packages were downloaded to, and then run the command "sudo dpkg -i
linux-*.deb" (without the quotation marks) in order to manually install
the three DEBs. Then reboot the system.

For a complete list of kernels, visit http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D

PS: for 32-bit systems, the 3 DEBs to be downloaded and installed are:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux-
headers-4.7.4-040704_4.7.4-040704.201609150330_all.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux-
headers-4.7.4-040704-generic_4.7.4-040704.201609150330_i386.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.4/linux-
image-4.7.4-040704-generic_4.7.4-040704.201609150330_i386.deb

If your system is hanging/freezing to the point that you can't even
login into the GUI, power off your computer, then turn it on again and
press the Esc key until you get into the GRUB menu. Afterwards, press
the E key in order to edit the grub menu, then go to the first instance
of the code "$vt_handoff" and add the "nomodeset" parameter right before
it.

Example:
=> Before = quiet splash $vt_handoff
=> After = quiet splash nomodeset $vt_handoff

After adding the "nomodeset" parameter, press the F10 key (or the Ctrl X
key combo). Linux will boot with Kernel Mode Setting (KMS) disabled,
then you will be able to log into the Graphical User Interface (GUI) and
then download and install a stable kernel.

Sorry for the long comment that is not a relevant info for those
investigating the bug. It just so other users know how to "deal" with
the bug while it's not fixed/removed from previous kernel versions.

[Yuri Ribeiro Sucupira]

@Timo Aaltonen (tjaalton): after reading your comment, I decided to
install kernel 4.4.0-23.41, but it isn't available on the repo anymore,
so I installed kernel 4.4.0-24 (if "that revert is already in the xenial
kernel since Ubuntu-4.4.0-23.41", then installing kernel 4.4.0-24
shouldn't be a problem). Then I ran some tests and my system "froze". I
had to press the power button of my laptop to shut it down (hardware
power off).

First I executed "DRI_PRIME=1 glxgears" on the shell: all I got was a
black screen. Then I executed "xscreensaver-demo" and previewed the
"Molecule" screensaver, twice: at the first time, nothing happened (as
usual. This is normal), but at the second time the screen locked and I
had to use the "Ctrl Alt F1" combo to switch to TTYS1 and restart
lightdm (with the command "sudo service lightdm restart"). Then I
returned to TTYS7 (Ctrl Alt F7) and hit the "Power off" (software)
button, but the system hanged, so I had to press the physical "power"
button of my laptop.

If someone builds some 4.4.X kernel with the "good commit"
e9bef455af8eb0e837e179aab8988ae2649fd8d3 (mentioned in comment #33)
applied/patched, I can test it and confirm if the bug is still there.

[Kernel-packages] [Bug 1579374] Re: amdgpu causes NULL pointer dereference when trying to use Topaz (Radeon R7 M265) GPU

[Yuri Ribeiro Sucupira]

As I reported here:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
amdgpu/+bug/1608042/comments/31

...my computer is exactly the same (Dell Inspiron 5448 laptop, BIOS A06,
hybrid graphics Intel Broadwell - module i915 + AMD Topaz XT R7
M260/M265 - module amdgpu) and after installing 64-bit XUbuntu 16.04
"Xenial" I got the same problem, because of the kernel 4.4.

I got rid of the kernel-AMD GPU issues after doing some reverse commit
and identifying that kernel 4.6-rc1 received a "good commit" that fixed
the problem.

I'm currently running 4.6-rc7, but I can confirm that from 4.6-rc1 ahead
the "NULL pointer dereference" bug's gone. From kernel 4.6-rc1 or newer
I'm able to execute "DRI_PRIME=1 glxgears" without experiencing any
issues.

Title:
  amdgpu causes NULL pointer dereference when trying to use Topaz
  (Radeon R7 M265) GPU

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  A Dell Inspiron 5448 / 0YDTG3 laptop (BIOS A06 10/12/2015), which used
  to work well with Ubuntu trusty and Ubuntu wily releases (using fglrx
  driver), presents multiple issues with Ubuntu xenial.

  When the amdgpu driver tries to activate the Radeon GPU, a NULL
  pointer dereference occurs, causing the caller process to hang. This
  practically causes the system to hang when trying a logoff or
  shutdown.

  The bug can be easily reproduced by calling:

  DRI_PRIME=1 glxgears

  Which hangs the glxgears process and causes the stacktrace attached
  below.

  The system also crashes with a kernel panic (capslock key blinking and
  system does not answer to magic SysRq keys) when coming back from a
  suspend.

  The bug reported in this forum post
  http://ubuntuforums.org/showthread.php?t=2318640 appears to be the
  same.

  Kernel 4.5.0-050400 from http://kernel.ubuntu.com/~kernel-
  ppa/mainline/v4.5-wily fixes the crashes and oopses, although the
  Radeon GPU still does not work (DRI_PRIME=1 glxgears opens a black
  window). However, at least the system can be used with the Intel GPU
  in a stable fashion.

[Yuri Ribeiro Sucupira]

"I think the flickering problem only occurs if you use two external
monitors with e-port-dock."

In my case, my laptop suddenly powers off. But another bug that happens
in it is this: after a while with Xscreensaver running, the screen
flickers and remains that way for some 3 extra seconds after I type my
password and the screen is unlocked.

Weird thing is that after the screen is unlocked, some 3 seconds later
the flickering stops.

Please see this bug report:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520040

This bug makes my Dell Latitude laptop shutdown (power off). In that bug
report I provided a lot of information about my system, logs and tests I
did. Currently, only kernel "3.13.0-36-generic" running module
"/lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko" doesn't
have this bug.

Hence, this bug is far from "solved" and shutting up dmesg definitely
won't solve it.

This is a mysterious bug affecting a LOT of machines. As I suggested at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520040, as a
temporary workaround I recommend downgrading to kernel
"3.13.0-36-generic".

Try it out and see if it is of any help.

[Kernel-packages] [Bug 1520040] Re: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

[Yuri Ribeiro Sucupira]

By the way: "dmesg |grep -i error" and "dmesg |grep -i lied" are two
other shell commands I run, too. Where I mentioned above that I didn't
find the bug I mean that besides running "dmesg |grep -i i915" I also
ran the two previously mentioned commands and got no results (meaning
that no "error" string neither "lied" string was found).

  Device: notebook Dell Inspiron 5548

  Operating system: 64-bit XUbuntu Linux 14.04 LTS

  Processor: Intel Core i7-5500U

  Kernel: 3.19.0-33-generic #38~14.04.1-Ubuntu SMP x86_64

  Video: dual chip. These are the two display controllers:
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:
  /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

  Notes:
  - "bdw" stands for "Broadwell"
  - "bpo", I believe, stands for "backport"

[Kernel-packages] [Bug 1520040] Re: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

[Yuri Ribeiro Sucupira]

Hello.

Happy New Year everyone.   :)

I have a doubt: I started testing these kernels and one of'em has the
following message in dmesg (shell command was 'dmesg | grep -i i915'):

[   11.547334] snd_hda_intel :00:03.0: bound :00:02.0 (ops
i915_audio_component_bind_ops [i915])

I understand that this isn't a bug (it seems that snd_hda_intel was
bound to the audio component of i915 and that's it), but since I'm not
100% sure about what this message actually means it doesn't hurt to ask.
Any consideration to be taken into account here?

Anyway, so far I've tested the following kernels and got the following
outputs from 'dmesg |grep -i i915':

1) v4.1.6-unstable:

[1.195451] [drm] Initialized i915 1.6.0 20150327 for :00:02.0 on minor 0
[2.311613] i915 :00:02.0: fb0: inteldrmfb frame buffer device
[2.311614] i915 :00:02.0: registered panic notifier
[8.605191] snd_hda_intel :00:03.0: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])

Because I am assuming that "snd_hda_intel :00:03.0: bound
:00:02.0 (ops i915_audio_component_bind_ops [i915])" isn't a bug, I
considered that the bug reported in this ticket is fixed in kernel
version "v4.1.6-unstable", hence I decided to test a previous (older)
kernel version: v4.0.6-wily.

2) v4.0.6-wily:

[1.243539] [drm] Initialized i915 1.6.0 20150130 for :00:02.0 on minor 0
[2.316114] i915 :00:02.0: fb0: inteldrmfb frame buffer device
[2.316115] i915 :00:02.0: registered panic notifier
[7.558016] snd_hda_intel :00:03.0: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])
[   34.302400] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU 
pipe A FIFO underrun

I considered that FIFO underrun a bug, hence I then decided to test a
newer kernel version: v4.1-rc7-unstable.

3) v4.1-rc7-unstable:

[1.194191] [drm] Initialized i915 1.6.0 20150327 for :00:02.0 on minor 0
[2.324857] i915 :00:02.0: fb0: inteldrmfb frame buffer device
[2.324858] i915 :00:02.0: registered panic notifier
[5.989937] snd_hda_intel :00:03.0: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])
[   26.618897] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU 
pipe A FIFO underrun

Same FIFO underrun issue, thus I then tested a newer kernel version:
v4.1.2-unstable.

4) v4.1.2-unstable:

[1.188288] [drm] Initialized i915 1.6.0 20150327 for :00:02.0 on minor 0
[2.296468] i915 :00:02.0: fb0: inteldrmfb frame buffer device
[2.296469] i915 :00:02.0: registered panic notifier
[7.502745] snd_hda_intel :00:03.0: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])

Assuming that "snd_hda_intel :00:03.0: bound :00:02.0 (ops
i915_audio_component_bind_ops [i915])" isn't a bug, I considered the bug
fixed in kernel version v4.1.2-unstable, and thus decided to test a
previous (older) kernel version: v4.1-wily.

5) v4.1-wily:

[1.176185] [drm] Initialized i915 1.6.0 20150327 for :00:02.0 on minor 0
[2.292596] i915 :00:02.0: fb0: inteldrmfb frame buffer device
[2.292597] i915 :00:02.0: registered panic notifier
[   11.547334] snd_hda_intel :00:03.0: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])

Again, since I'm assuming that "snd_hda_intel :00:03.0: bound
:00:02.0 (ops i915_audio_component_bind_ops [i915])" isn't a bug,
I'm considering that the vug is fixed in kernel version v4.1-wily.

Is it ok so far? If it is, I am very close to finding out in which
kernel version the bug fix was commited.

Well, it's been ~24 hours since I started using kernel"4.4-rc2+cod1".

My notebook was kept "on" for over 16 of these 24 hours: 8h yesterday +
8h today. So far, no subtle poweroff happened. I restarted the system a
couple of times, today and yesterday, and I also powered off the
notebook. No issues detected.

Here's the current output for 'dmesg |grep -i i915' (the notebook's been on for 
the last 8 hours):

[Yuri Ribeiro Sucupira]

Wow, that seems a lot of work. I've never did it before in my life, but
ok, let's see if I can do it.

I'll need some help here, though, 'coz I'm not 100% sure if the kernel
list I created is correct. Could you please confirm this to me?

If I understood the instructions correctly, according with
"ProcVersionSignature: Ubuntu 3.19.0-33.38~14.04.1-generic 3.19.8-ckt7"
and "http://people.canonical.com/~kernel/info/kernel-version-map.html;
the mainline kernel version for "3.19.0-33-generic" (which shipped with
my notebook) is kernel "3.19.8-ckt7", hence the botton of the kernel
list must be "v3.19.8-ckt7-vivid".

Also, because the bug was fixed in upstream kernel "v4.4-rc2+cod1-wily",
it has to be on the top of the list, thus I am assuming that the kernel
list for reverse commit bisect has to be this one:

v4.4-rc2+cod1-wily

v3.19.8-ckt8-vivid
v3.19.8-ckt7-vivid

Is my line of thought correct? Hence, is the above list correct?

As soon as I have a confirmation, I'll begin tracking down the commit
that fixed the bug.

3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:
  /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

  Notes:
  - "bdw" stands for "Broadwell"
  - "bpo", I believe, stands for "backport"

[Kernel-packages] [Bug 1520040] Re: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

[Yuri Ribeiro Sucupira]

HI. Today I accessed http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D but the very top line at the top of the page was a
link to http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc2-wily/,
which doesn't have kernel DEB packages (except for linux-
headers-4.4.0-040400rc2_4.4.0-040400rc2.201511251301_all.deb, but this
is only the kernel headers, I couldn't find any kernel image). Thus I
proceeded to http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-
next/ where the most recent folder with available DEB packages currently
is http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-
next/2015-11-21-wily/

>From http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-
next/2015-11-21-wily/ I downloaded and installed the following packages:

 linux-image-4.3.0-997-generic_4.3.0-997.201511202100_amd64.deb

 linux-headers-4.3.0-997-generic_4.3.0-997.201511202100_amd64.deb

I was able to boot this kernel. Here's the result of some commands:

'uname -a':

I noticed that 'fglrx_updates.ko' (which seems to be the AMD GPU driver)
probably is a proprietary driver and thus wasn't loaded by the kernel (I
noticed some dkms error messages related to it, during kernel
installation, probably because of restrictions at the driver's dkms.conf
file), which caused kernel '4.3.0-997-generic' to try to load
/lib/modules/4.3.0-997-generic/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko.
Because 'amdgpu.ko' wasn't loaded either, I was unable to run the 'AMD
Catalyst Control Center' (shell command: amdcccle). But the kernel did
detect the AMD GPU:

'aticonfig --list-adapters':
 * 0. 04:00.0 AMD Radeon R7 M260

 * - Default adapter (managed by
/lib/modules/4.3.0-997-generic/kernel/drivers/gpu/drm/i915/i915.ko)

'lspci |grep -i amd':

04:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz
XT [Radeon R7 M260]

'i915.ko' was loaded and 'amdgpu.ko' depends on it. Here's the output for 
'lsmod |grep -i i915':
 i915 --- 1204224 --- 5
 i2c_algo_bit --- 16384 --- 2 --- i915,amdgpu

 drm --- 356352 --- 8 --- ttm,i915,drm_kms_helper,amdgpu
 video --- 36864 --- 3 --- i915,dell_wmi,dell_laptop

So, in a nutshell: looks like the kernel '4.3.0-997-generic' is doing ok
with its module 'i915.ko'. I will keep testing it for a while just to
make sure, but so far 'dmesg' hasn't shown me any message like
'[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied
(SDE)!' for kernel '4.3.0-997-generic'.

"amdcccle" (AMD Catalyst Control Center): opens a window with an error

"There was a problem while attempting to start Catalyst Control Center
Linux Edition. It may have been caused by the following:

 No AMD graphics driver installed, or AMD graphics driver not working
properly.

 Install the proper AMD driver to your AMD hardware, or configure it
with 'aticonfig'."

Well, this pretty much confirms to me that "fglrx_updates" is definitely
a proprietary AMD GPU driver and thus doesn't work with these kernels,
as explained in https://wiki.ubuntu.com/Kernel/MainlineBuilds

I will keep this kernel running for the next hours and report back if
any message like "[drm:gen8_irq_handler [i915]] *ERROR* The master

[Kernel-packages] [Bug 1520040] Re: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

[Yuri Ribeiro Sucupira]

I'm not 100% sure if "Confirmed" refers to the latest / upstream kernel
I'm testing (4.3.0-997-generic) or to the one in which I detected the
bug in (kernel 3.19.0-33-generic). But I'm assuming that it refers to
'4.3.0-997-generic', thus I marked this bug as "Confirmed" (although it
seems to be fixed in the last upstream kernel).

I just would like to test this upstream kernel it with both
'fglrx_updates' and 'i915'/'i915_bpo' simultaneously loaded. I'm under
the impression that maybe there's an IRQ conflict between the default
GPU (handled by Broadwell module i915*) and the AMD GPU (handled by AMD
module fglrx_updates).

  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:

[Kernel-packages] [Bug 1520040] Re: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

[Yuri Ribeiro Sucupira]

Thank you. I've just run the apport-collect app as instructed.

Note: until Nov 27 02:32:01 AM UTC-2 (my local time, equivalent to
04:32:01 AM UTC) I was running kernel 3.19.0-33-generic as my default
O.S. kernel, but then my notebook subtly powered off once more, thus
causing me to decide to boot with kernel 3.13.0-36-generic by default.
However, before running 'apport-collect 1520040' I booted the machine
with kernel 3.19.0-33-generic again. Please let me know if it's
interesting that I keep my system running only kernel 3.19.0-33-generic
for a while, in order to further generate useful logs.

Title:
  [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt
  lied (SDE)!

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Device: notebook Dell Inspiron 5548

  Operating system: 64-bit XUbuntu Linux 14.04 LTS

  Processor: Intel Core i7-5500U

  Kernel: 3.19.0-33-generic #38~14.04.1-Ubuntu SMP x86_64

  Video: dual chip. These are the two display controllers:
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:

Bug description:
  Device: notebook Dell Inspiron 5548

  Operating system: 64-bit XUbuntu Linux 14.04 LTS

  Processor: Intel Core i7-5500U

  Kernel: 3.19.0-33-generic #38~14.04.1-Ubuntu SMP x86_64

  Video: dual chip. These are the two display controllers:
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:
  /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

  Notes:
  - "bdw" stands for "Broadwell"
  - "bpo", I believe, stands for "backport"

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:
  /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

  Notes:
  - "bdw" stands for "Broadwell"
  - "bpo", I believe, stands for "backport"

Title:
  [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt
  lied (SDE)!

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Device: notebook Dell Inspiron 5548

  Operating system: 64-bit XUbuntu Linux 14.04 LTS

  Processor: Intel Core i7-5500U

  Kernel: 3.19.0-33-generic #38~14.04.1-Ubuntu SMP x86_64

  Video: dual chip. These are the two display controllers:
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:
  /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

  Notes:
  - "bdw" stands for "Broadwell"
  - "bpo", I believe, stands for "backport"

Title:
  [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt
  lied (SDE)!

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Device: notebook Dell Inspiron 5548

  Operating system: 64-bit XUbuntu Linux 14.04 LTS

  Processor: Intel Core i7-5500U

  Kernel: 3.19.0-33-generic #38~14.04.1-Ubuntu SMP x86_64

  Video: dual chip. These are the two display controllers:
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:
  /lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

  Notes:
  - "bdw" stands for "Broadwell"
  - "bpo", I believe, stands for "backport"

[Kernel-packages] [Bug 1520040] [NEW] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

[Yuri Ribeiro Sucupira]

Public bug reported:

Device: notebook Dell Inspiron 5548

Operating system: 64-bit XUbuntu Linux 14.04 LTS

Title:
  [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt

Status in linux-lts-vivid package in Ubuntu:

Bug description:
  Device: notebook Dell Inspiron 5548

  Operating system: 64-bit XUbuntu Linux 14.04 LTS

  Processor: Intel Core i7-5500U

  Kernel: 3.19.0-33-generic #38~14.04.1-Ubuntu SMP x86_64

  Video: dual chip. These are the two display controllers:
  - Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

  Problem: my notebook's operating system is switching to runlevel 0
  (power off) randomly, subtly and thus unexpectedly. And if I 'cat
  /var/log/kern.log |grep -i i915' I get a lot of "[drm:gen8_irq_handler
  [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!"
  messages. I'm under the impression that either the kernel or the
  kernel module "i915_bpo" is buggy.

  My notebook's problem can't be related to overheating, because it's a
  brand-new notebook (less than 1 month old) and I've already monitored
  its temperature parameters: nothing abnormal is happening. Also, I'm
  using a cooling laptop base/pad.

  Other kernels I've tested, with which the same issue happens:
  - 3.19.0-18-generic (kernel module: i915_bpo)
  - 3.19.0-23-generic (kernel module: i915_bpo)
  - 3.19.0-28-generic (kernel module: i915_bpo)
  - 4.2.0-18-generic (kernel module: i915)

  Temporary workaround: I downgraded to kernel "3.13.0-36-generic",
  which isn't buggy with its "i915_bdw.ko" (version 3.0) kernel object
  (module). Full path for this module:

[Yuri Ribeiro Sucupira]

Hi, Christopher, thank you for your reply.
I'm currently running kernel "3.13.0-36-generic", which doesn't have any issue 
with module "i915_bdw.ko". I know I'll have to upgrade the kernel in order to 
make the issue come up again. My doubt is: which kernel shall I upgrade my 
system to? Shall I upgrade to kernel "3.19.0-33-generic" (module 
"i915_bpo.ko")? Or kernel "4.2.0-18-generic" (module "i915.ko")? Or shall I 
switch kernels and file a bug for each one of'em?
I can do both (file a bug for 3.19.0-33-generic and another for 
4.2.0-18-generic), it's not a problem. I'm just not sure if it's necessary. 
Please let me know which option is the best and I'll do it.
[]'s
Yuri

[Yuri Ribeiro Sucupira]

This bug also affects me. Well, now it doesn't anymore, because I've
downgraded my system kernel.

Device: notebook Dell Inspiron 5548

Operating system: 64-bit XUbuntu Linux 14.04

Processor: Intel Core i7-5500U

Video: dual chip. These are the two display controllers:
- Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display 
controller 3300Hz (requires kernel module / device driver "fglrx"); and
- Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 
3300Hz (requires kernel module / device driver "i915").

Problem: the message "[drm:gen8_irq_handler [i915_bpo]] *ERROR* The
master control interrupt lied (SDE)!" floods my dmesg. If I "cat
/var/log/kern.log |grep -i i915" i see a huge amount of messages exactly
like this one, hence I can only assume that the kernel module i915_bpo
is buggy. Also, my notebook was subtly powering off from time to time
(unrelated with overheat, I'm pretty sure 'coz I've already monitored
temperature parameters and also 'coz I'm using a cooling laptop
base/pad).

Kernels I've tested which have this issue:
- 3.19.0-18-generic
- 3.19.0-23-generic
- 3.19.0-28-generic
- 3.19.0-33-generic
- 4.2.0-18-generic

All of them have the same problem: the kernel module "i915.ko" (in
4.2.0-18-generic) and the kernel module "i915_bpo.ko" (in kernels
3.19.0-??-generic) cause subtle system shutdown (halt / poweroff) in my
notebook.

Solution: I downgraded to kernel 3.13.0-36-generic, which isn't buggy
with its "i915_bdw.ko" (version 3.0) kernel object (module). Full path
for this module:
/lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

Notes:
- "bdw" stands for "Broadwell"
- "bpo", I believe, stands for "backport"

IMO, this bug is pretty serious and is taking a lot of time to get
fixed: my notebook could get damaged if it kept subtly powering off on
an everyday basis like it was doing because of this bug. Hence, my
strong suggestion to those who are experiencing this issue is to
downgrade to a stable kernel version (I recommend kernel
3.13.0-36-generic.

If you don't want to downgrade your kernel: become root ('sudo su'),
then open '/etc/default/grub' for edition (e.g.: 'gedit
/etc/default/grub'), then add the 'nomodeset' option to
"GRUB_CMDLINE_LINUX_DEFAULT=" (e.g.:
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"), then save the file, exit the
text editor and, still as root, run the command 'update-grub && telinit
6'. Your GRUB will be updated and your system will be restarted. After
that you won't be able to see OpenGL graphics anymore (e.g. Xscreensaver
openGL screensavers won't load), but your system will stop subtly
powering off.

3300Hz (requires kernel module / device driver "i915").

Problem: the message "[drm:gen8_irq_handler [i915_bpo]] *ERROR* The
master control interrupt lied (SDE)!" floods my dmesg, and from time to
time my system crashes and my computer powers off. If I 'cat
/var/log/kern.log |grep -i i915' i see a huge amount of messages exactly
like this one, hence I can only assume that the kernel module i915_bpo
is buggy (or these kernels are buggy while they interact with that
kernel module). My notebook is subtly powering off from time to time
(unrelated with overheat, I'm pretty sure 'coz I've already monitored
temperature parameters and also 'coz I'm using a cooling laptop
base/pad, besides the fact that my notebook is brand-new: only 1 week
old).

Kernels I've tested which have this issue:
- 3.19.0-18-generic

4.2.0-18-generic) and the kernel module "i915_bpo.ko" (in kernels
3.19.0-??-generic) randomly cause subtle system shutdown (halt /

Notes:
- "bdw" stands for "Broadwell"
- "bpo", I believe, stands for "backport"

IMO, this bug is pretty serious and is taking a lot of time to get
fixed: my notebook could get damaged if it kept subtly powering off
several times a day, on an everyday basis, like it was doing because of
this bug. Hence, my strong suggestion to those who are experiencing this
issue is to downgrade to a stable kernel version (I recommend kernel
3.13.0-36-generic).
