I know it's not a supported kernel, but I think this issue should be of interest to the maintainers. Otherwise so far this kernel has been doing great in terms of i915 stability. Today I encountered a system lockup which appears to again be related to the i915 driver.

Public bug reported: I'm running the currently latest kernel 4.6.0-040600rc7-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc7-wily/ because I've had ongoing issues with graphics (i915) on a new Skylake Thinkpad T460s. I know it's not a supported kernel, but I think this issue should be of interest to the maintainers. Otherwise so far this kernel has been doing great in terms of i915 stability. Today I encountered a system lockup which appears to again be related to the i915 driver.

[Kernel-packages] [Bug 1520040] Re: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
Just wanted to add that this message no longer appears on machines running the 4.4.0 kernel from Xenial, whereas it still appeared in the latest 4.2.0 kernel on wiley machines. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1520040 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" ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.19.0-33-generic 3.19.0-33.38~14.04.1 ProcVersionSignature: Ubuntu 3.19.0-33.38~14.04.1-generic 3.19.8-ckt7 Uname: Linux 3.19.0-33-generic x86_64 NonfreeKernelModules: wl fglrx ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 CurrentDesktop: XFCE Date: Wed Nov 25 23:44:39 2015 InstallationDate: Installed on 2015-11-03 (22 days ago) InstallationMedia: Xubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) SourcePackage: linux-lts-vivid UpgradeStatus: No upgrade log present (probably fresh install) --- ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 AudioDevicesInUse: USERPID ACCESS COMMAND /dev/snd/controlC0: yuriyrs2832 F pulseaudio /dev/snd/controlC1: yuriyrs2832 F pulseaudio CurrentDesktop: XFCE DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=a08f36f9-0611-4894-9da9-8b1dcc960a86 InstallationDate: Installed on 2015-11-03 (24 days ago) InstallationMedia: Xubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) MachineType: Dell Inc.
