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

apport information

** Tags added: apport-collected

** Description changed:

  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 33000000Hz (requires kernel module / device driver "fglrx"); and
  - Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 33000000Hz (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"
