Dawid Wróbel, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1586046 Title: Unclaimed register detected after reading register 0x65f10 Status in linux package in Ubuntu: Incomplete Bug description: After booting to newest kernel, I see following in dmesg: [ 28.156951] WARNING: CPU: 3 PID: 2005 at /build/linux-FvcHlK/linux-4.4.0/ubuntu/i915/intel_uncore.c:649 __unclaimed_reg_debug+0x80/0x90 [i915_bpo]() [ 28.156953] Unclaimed register detected after reading register 0x65f10 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-22-generic 4.4.0-22.40 ProcVersionSignature: Ubuntu 4.4.0-22.40-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC0D3p: cromo 1941 F...m pulseaudio /dev/snd/controlC0: cromo 1941 F.... pulseaudio /dev/snd/seq: timidity 1020 F.... timidity Date: Thu May 26 09:46:38 2016 HibernationDevice: RESUME=UUID=3cd6beac-9b2b-4af8-9004-fdec2b01f2df InstallationDate: Installed on 2013-04-24 (1128 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130423.1) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 005: ID 0c45:670c Microdia Bus 001 Device 004: ID 04f3:20d0 Elan Microelectronics Corp.
