[Kernel-packages] [Bug 1535048] Re: i915 driver seems to cause system crash at random
*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 New test result today seems to be a intel P-state related problem. I had reverted everything to their default state, with only the following changes in TLP settings: /etc/default/tlp # Set Intel P-state performance: 0..100 (%) # Limit the max/min P-state to control the power dissipation of the CPU. # Values are stated as a percentage of the available performance. # Requires an Intel Core i processor with intel_pstate driver. CPU_MIN_PERF_ON_AC=100 CPU_MAX_PERF_ON_AC=100 CPU_MIN_PERF_ON_BAT=100 CPU_MAX_PERF_ON_BAT=100 Now the machine never crashed no matter what tricked I played against it. This workaround seemed to work both under a normal Linux kernel and a realtime kernel. I guess the crash was triggered by flipping the P-state to save power. In the previous report I was using WebGL Aquarium to do the test, which has a rather linear stress. But later when I was using Krita, whose stresses on the CPU comes in spikes, the old workaround failed to work. When connecting to an external monitor, it also did not crash anyway but I guess it was using full power all the way because of the dualview requires that much power. -- 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/1535048 Title: i915 driver seems to cause system crash at random Status in libdrm package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: the system crashes totally at random... sometimes after hours sometimes after minutes... hardware reboot is required no problem under windows before it crashes though it always screw up the video for a few seconds lspci -nnk | egrep -i '3d|aphics|display|nouveau|nvidia|radeon|trident|vesa|vga'; uname -a; Xorg -version; sudo apt-get update; sudo apt-get install mesa-utils hardinfo fbset nux-tools; sudo fbset -i; apt-cache show xserver-xorg | grep Version; xrandr; fglrxinfo; nvidia-settings -g |head -n 30 ; sudo lshw -short; sudo lshw -C display; dpkg -l | egrep -i 'fgl|intel|mesa|mesa-utils|nvidia|nouveau|radeon|trident|video-ati'; cat /etc/lsb-release; dmesg | egrep -i 'abort|ailed|bug|error|fail|fgl|GLX|GPU|intel|missing|nouveau|NVIDIA|radeon|segment|trident|VESA|VGA|wfb|\(EE\)|\(WW\)'; cat /proc/cpuinfo | grep -I model; cat /var/log/Xorg.0.log | egrep -i 'abort|ailed|bug|display|error|fail|fgl|GLX|GPU|intel|issing|nouveau|nvidia|radeon|segment|trident|VESA|VGA|wfb|\(EE\)|\(WW\)'; sudo dmidecode|egrep 'anufact|roduct|erial|elease'; cat /etc/X11/xorg.conf; /usr/lib/nux/unity_support_test -p; ubuntu-support-status ; sudo lsmod 00:02.0 VGA compatible controller [0300]: Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) Linux box 4.3.0-5-generic #16-Ubuntu SMP Wed Dec 16 23:33:25 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux X.Org X Server 1.17.3 Release Date: 2015-10-26 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.19.0-33-generic x86_64 Ubuntu Current Operating System: Linux box 4.3.0-5-generic #16-Ubuntu SMP Wed Dec 16 23:33:25 UTC 2015 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.3.0-5-generic root=UUID=1406f1b3-ed81-4320-a7df-aba3cb5d60e6 ro quiet splash vt.handoff=7 Build Date: 25 November 2015 04:17:13PM xorg-server 2:1.17.3-2ubuntu2 (For technical support please see http://www.ubuntu.com/support) Current version of pixman: 0.33.6 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 I did a few more tests. On my system, the combination of a realtime (lowlatency) kernel and certain tlp settings fixed the random crash. Although the side effect was the machine can get very hot because CPU threads cannot be turned off. Processor: Intel® Core™ i7-6567U Graphics: Intel® Iris Graphics 550 (Skylake GT3e) Linux kernel: 4.11.12-1-rt16-MANJARO TLP modified settings (/etc/default/tlp): SCHED_POWERSAVE_ON_AC=0 ENERGY_PERF_POLICY_ON_AC=normal Note: this combination also solved the intel 8265 bluetooth random disconnection and reconnection failure on this machine. All these tests were carried out on Manjaro, but I did suffered similar problem when I was testing Ubuntu 17.10. I hope my information can be helpful. -- 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/1535048 Title: i915 driver seems to cause system crash at random Status in libdrm package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: the system crashes totally at random... sometimes after hours sometimes after minutes... hardware reboot is required no problem under windows before it crashes though it always screw up the video for a few seconds lspci -nnk | egrep -i '3d|aphics|display|nouveau|nvidia|radeon|trident|vesa|vga'; uname -a; Xorg -version; sudo apt-get update; sudo apt-get install mesa-utils hardinfo fbset nux-tools; sudo fbset -i; apt-cache show xserver-xorg | grep Version; xrandr; fglrxinfo; nvidia-settings -g |head -n 30 ; sudo lshw -short; sudo lshw -C display; dpkg -l | egrep -i 'fgl|intel|mesa|mesa-utils|nvidia|nouveau|radeon|trident|video-ati'; cat /etc/lsb-release; dmesg | egrep -i 'abort|ailed|bug|error|fail|fgl|GLX|GPU|intel|missing|nouveau|NVIDIA|radeon|segment|trident|VESA|VGA|wfb|\(EE\)|\(WW\)'; cat /proc/cpuinfo | grep -I model; cat /var/log/Xorg.0.log | egrep -i 'abort|ailed|bug|display|error|fail|fgl|GLX|GPU|intel|issing|nouveau|nvidia|radeon|segment|trident|VESA|VGA|wfb|\(EE\)|\(WW\)'; sudo dmidecode|egrep 'anufact|roduct|erial|elease'; cat /etc/X11/xorg.conf; /usr/lib/nux/unity_support_test -p; ubuntu-support-status ; sudo lsmod 00:02.0 VGA compatible controller [0300]: Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) Linux box 4.3.0-5-generic #16-Ubuntu SMP Wed Dec 16 23:33:25 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux X.Org X Server 1.17.3 Release Date: 2015-10-26 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.19.0-33-generic x86_64 Ubuntu Current Operating System: Linux box 4.3.0-5-generic #16-Ubuntu SMP Wed Dec 16 23:33:25 UTC 2015 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.3.0-5-generic root=UUID=1406f1b3-ed81-4320-a7df-aba3cb5d60e6 ro quiet splash vt.handoff=7 Build Date: 25 November 2015 04:17:13PM xorg-server 2:1.17.3-2ubuntu2 (For technical support please see http://www.ubuntu.com/support) Current version of pixman: 0.33.6 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

[Kernel-packages] [Bug 1136110] Re: USB Audio Codec choppy playback
I thoroughly tested the patches when the bug happened to me before. The same kind of stuttering never happened again after the fix was released. I suppose the newer reports are not related to this bug. Please understand not all choppy audio has the same source. You may troubleshoot over these things: 1) Turn off Wireless and Bluetooth. CSR Bluetooth adapters are more stable. Broadcom to my experience is very bad at this. Realtek wifi chips are kinda bad, too. 2) Do not use USB hub, or make sure it is sufficiently powered (>500mA per port, >2A DC adapter). 3) Make sure the playback samplerate is native of the device. Pulseaudio's SRC could introduce stuttering. If your DAC is 48K by default and you output 44.1K to Pulseaudio, it can chop things up. 4) Do not use aggressive power save options in your BIOS. 5) Try plug the DAC on USB2.0 only ports, not USB3.0 ports. Many USB3.0 ports are running on 3rd party chips.

It's said that such a DAC hosts the clock itself (USB Device Host). An ordinary DAC, so called "Synchronous USB DAC", uses the clock hosted by the mother board, which is not affected by this bug. When this bug affects an asynchronous USB DAC, the audio played by the DAC is constantly interrupted. The playback itself does not stop, but the output becomes discontinous, filling with constant crackling noises, destroying everything the DAC plays. Using CLI command grep device.buffering to get the buffer from the devices, those affected kernels are reporting back a different number to the unaffected devices. The choppy noise is very similar to the situation when buffer size is not correctly set. I have tested four USB DACs, two Asynchronous and two Synchronous.
