[Kernel-packages] [Bug 1738736] Re: ACPI error message flooding syslog
Has there been any progress on this. I still have the same problem on both kernel 4.15 and 5.4. I still have to modify logrotate to limit logging or more recently I have tried stopping the logging of any errors which was not as simple as I expected as rsyslog uses socket activation under systemd. So whenever there is a log message coming in, rsyslog will be started on demand. The unit is named syslog.socket. So to stop the rsyslog service one needs to stop both units: systemctl stop syslog.socket rsyslog.service or completely to disable logging from the next boot by: systemctl disable syslog.socket rsyslog.service None of these are satisfactory long term solutions -- 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/1738736 Title: ACPI error message flooding syslog Status in linux package in Ubuntu: Confirmed Bug description: This message : Dec 18 09:20:13 tignasse kernel: [ 85.652805] ACPI Error: Needed type [Reference], found [Integer] 99eae08481f8 (20170531/exresop-103) Dec 18 09:20:13 tignasse kernel: [ 85.652831] ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20170531/dswexec-461) Dec 18 09:20:13 tignasse kernel: [ 85.652847] ACPI Error: Method parse/execution failed \_SB.PCI0.LPCB.H_EC._Q50, AE_AML_OPERAND_TYPE (20170531/psparse-550) Is flooding my syslog at a pace of on message every 200 ms !

[Kernel-packages] [Bug 1488426] Re: High CPU usage of kworker/ksoftirqd
I have tried the test patch provided by Mathias Nyman in http://linux- kernel.2935.n7.nabble.com/TESTPATCH-v2-xhci-fix-usb2-resume-timing-and- races-tc1250796.html#a1256745 and rebuilt a Wily 4.2 kernel and that has prevented High CPU usage of kworker/ksoftirqd under all the circumstances I have tried. Note this is marked as a TESTPATCH and Mathias Nyman mentions his intention is to " do some minor cleanups and add it to the queue ". At best it will be in the 4.4 kernel and then available for backports but it good to know that there is a solution in hand. @acelan Is there any way for you to also push the Mathias Nyman patch into the ubuntu kernel, assuming it also solves your original problem. Then normal users can just use an updated ubuntu kernel to get rid of this issue. As it is a timing and race problem it may well turn out to have a much wider impact than current reports show, in particular as it seems to affect Skylake 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/1488426 Title: High CPU usage of kworker/ksoftirqd Status in HWE Next: New Status in linux package in Ubuntu: In Progress Bug description: kworker consuming 71.5% cpu resource ksoftirqd consuming 28.9% cpu resource It leads to power consumption issue and sometimes leads to BT does not work.

[Kernel-packages] [Bug 1488426] Re: High CPU usage of kworker/ksoftirqd
I have carried out some more comprehensive tests using the kernel in #4 over the weekend and found it does improve my situation far more than my initial quick test showed. Most of the rather bizarre behaviour has gone include the changes with power from battery to external and the importance of suspending. Once kworker spinning has started it can now be _predictably_ stopped when using your kernel by: Any USB 2 device being plugged into any USB port or a USB 3 device plugged into the USB 2 port The internal Bluetooth being turned on so that it shows up as USB device The internal Web cam being used (by cheese during my test). Note running the web cam does not change what is shown by lsusb -t, everything else which stops spinning shows as a new device being connected in dmesg and appears in lsusb. Although the kernel in #4 does not completely solve the problem it is obviously addresses the correct area and in my case makes the machine usable without having anything plugged into a usb port, keeping bluetooth on is sufficient. @AceLan What is the status of the patch and other work on the issue? Is there anything else I can do to progress the work? -- 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/1488426 Title: High CPU usage of kworker/ksoftirqd Status in HWE Next: New Status in linux package in Ubuntu: In Progress Bug description: kworker consuming 71.5% cpu resource ksoftirqd consuming 28.9% cpu resource It leads to power consumption issue and sometimes leads to BT does not work.

[Kernel-packages] [Bug 1488426] Re: High CPU usage of kworker/ksoftirqd
I also have a similar problem which does Not seem to be solved by the patched kernel although the perf report looks very similar and plugging in a USB device clears the problem. The starting and inhibiting of the kworker spinning is very specific and rather bizare on my new Skylake machine running Linux Mint 17.3 beta (Cinnamon 2.8 desktop) with kernels between 3.19 and 4.2 during test. It only starts when external power is off and the machine is suspended/resumed - I have not so far been able to provoke it any other way. If power is restored excess usage stops but restarts if power unplugged. If power is on and a suspend/resume cycle is carried out external power can be unplugged without the excess usage. Any USB 2 device stops the excess usage when plugged into the USB2 port including USB3 devices. USB 3 devices plugged into a USB3 port do not stop the power usage. Turning on the webcam stops the usage as long as it is on - the webcam is on the usb2 hub Turning Bluetooth off and on with the function key stops the high usage as long as it still remains on. Software disabling and enabling does not work.

[Kernel-packages] [Bug 1245226] Re: HDMI: audio-video playback too fast
Christopher Penalver, life is too short to proliferate bug reports when there is an existing one with all the background. In my opinion what is needed is crosslinking and consolidation rather than proliferation so a full picture emerges and the appropriate people address it. It is, for example, also being looked at by the kernel team at https://bugzilla.kernel.org/show_bug.cgi?id=60769 which has further links to places the problem has been reported. ** Bug watch added: Linux Kernel Bug Tracker #60769 http://bugzilla.kernel.org/show_bug.cgi?id=60769 -- 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/1245226 Title: HDMI: audio-video playback too fast Status in “linux” package in Ubuntu: Invalid Bug description: After upgrading to Ubuntu 13.10, selecting HDMI as audio output device is broken.

[Kernel-packages] [Bug 1245226] Re: HDMI: audio-video playback too fast
This should still be reopened as it occurs for me on a Chillblast Defiant (Haswell/Optimus Architecture, Core i7 Processor and nVidia GTX 765M graphics) with Mint 17 running kernel 3.13.0-24 and I have also tried the ubuntu mainline 3.14.4 kernel. In both cases HDMI sound is about 20% fast whilst switching to normal audio output immediately slows it down. Switching graphics processor makes no difference. Kernel 3.10.33 works fine as did 3.8.0 in Mint 15. We definitely have a regression here somewhere between 3.10.33 and 3.13.0 -- 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/1245226 Title: HDMI: audio-video playback too fast Status in “linux” package in Ubuntu: Invalid Bug description: After upgrading to Ubuntu 13.10, selecting HDMI as audio output device is broken.

[Kernel-packages] [Bug 1218547] Re: Clevo W350ST brightness keys don't work on Kubuntu
I have the same problem on a Clevo W230ST based machine running Saucy 13 10. Exactly the same symtoms and print out of ls /sys/class/backlight both using 3.11 and a 3.8 kernel on a LiveUSB. The keys will reduce the backlight but not increase leaving one completely in the dark. I am running Bumblebee and there is also a problem with bbswitch (an important part of bumblebee) not getting the correct ACPI handles but it seems unrelated to me. -- 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/1218547 Title: Clevo W350ST brightness keys don't work on Kubuntu Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: Confirmed Bug description: The Fn+F8 and Fn+F9 keys are not working on my Clevo W350ST with Kubuntu Raring to change screen brightness of the internal laptop screen.
