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_4.3.0-997.201511202100_all.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': Linux yurix 4.3.0-997-generic #201511202100 SMP Sat Nov 21 02:02:46 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux 'dmesg |grep -i i915': [ 1.175639] [drm] Initialized i915 1.6.0 20151120 for 0000:00:02.0 on minor 0 [ 2.343450] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device [ 13.974419] snd_hda_intel 0000:00:03.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) (most recent event in dmesg was rcreated @ [ 1282.427420]) 'dmesg |grep -i amd': [ 0.000000] AMD AuthenticAMD [ 0.000000] RAMDISK: [mem 0x34978000-0x364b3fff] [ 1.143551] [drm] amdgpu kernel modesetting enabled.

[ 1.224944] amdgpu: probe of 0000:04:00.0 failed with error -2 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_kms_helper --- 135168 --- 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'. -- 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: Confirmed 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 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" 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: USER PID ACCESS COMMAND /dev/snd/controlC0: yuriyrs 2832 F.... pulseaudio /dev/snd/controlC1: yuriyrs 2832 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.
