[Kernel-packages] [Bug 1987829] Re: LG Gram 12gen high CPU use when USB-C/TB is in use
This problem is a real nightmare. Basically, a LG-gram is unusable when the power cable is connected. A while back, the issue would only happen when an SD card was plugged in. I got into the habit of removing my backup card. Now, it happens w/ or w/out the SD card.

An observed drawback from this solution is that is breaks the functionality of the screen brighness buttons: it still works, but you can hold it, and it also has a big delay in applying each setting - This doesn't bother me as I already use some scripts with a custom keyboard shortcut to set the brighness of all my displays at once. Another solution is unmasking the GPE interrupts not through a kernel parameter, but after boot with: echo unmask > /sys/firmware/acpi/interrupts/gpe6E - This way the brightness button issues don't manifest. Furthermore, setting the kernel parameter acpi_mask_gpe=0x6E, it could be affecting idle power draws if the values returned by GPE are used to put cpus into idle states. Thankfully the issue only happens when the laptops are charging, so it wouldn't kill battery life. >From the kernel documentation I could find: acpi_mask_gpe= [HW,ACPI]Due to the existence of _Lxx/_Exx, some GPEs triggeredby unsupported hardware/firmware features can result inGPE floodings that cannot be automatically disabled bythe GPE dispatcher.This facility can be used to prevent such uncontrolledGPE floodings.Format: or So the documentation is aligned with the observations of the fix/workaround. -- Furthermore, there is another possible fix: journalctl seems to output many ACPI errors, probably due to the miscommunication between Linux thinking it can probe for thermal info on a device which did not register a handler to do so. The ACPI issue is a flood caused by the int3403 temp sensor library, which can be unloaded from the kernel without any other visible system effect sudo rmmod int3403_thermal is how it's unloaded A permanent fix seems to be patching the int3403 library to add something like if (sensorNotPresent) then skip or unregister until next launch -- There seems to be yet another issue related to this: power usage goes way up to around 10W at idle (instead of like 3W) and there's a kernel thread with high load (visible in powertop) related to the i915 graphics driver The solution seems to be: echo 1 > /sys/kernel/debug/dri/1/i915_hpd_short_storm_ctl That should be run on every boot to stop another interrupt flooding from happening, but this solution: it might break multi-stream transport on DisplayPort - the short storm detection is enabled by default unless multi-stream transport is supported -- Another finding: The laptop is by default running on "Silent mode" which can be disabled by: echo 1 > /sys/devices/platform/lg-laptop/fan_mode -- The laptop indeed seems to have no BIOS updates. -- Another issue seems to be that on some distros the laptop might thermal throttle to very low wattages, and the fix is: systemctl disable --now thermald -- 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/1987829 Title: LG Gram 12gen high CPU use when USB-C/TB is in use Status in l
[Kernel-packages] [Bug 1987829] Re: LG Gram 12gen high CPU use when USB-C/TB is in use
Can confirm the issue on my LG Gram 17Z90Q-K (2022 model) running Manjaro (Arch) with Kernels: 6.4.2-3 (latest version I have available on my system) 6.1.38-1 (LTS) Happens both connected to my Thunderbolt 3 dock that also charges the computer, or to the power supply. Doesn't happen when running on battery power. Doesn't happen on my LG gram from 2021. 1. I didn't find any reports of this issue for the 2023 models. Did anyone? I believe that we need either a Linux Kernel patch or a BIOS update, but there doesn't seem to be any updates to the BIOS of the 2022 lined up of LG Gram. 2. How can we get this fixed? Who can save us!? 3. Are there any workarounds that can be programmatically applied? Someone here: https://bugzilla.kernel.org/show_bug.cgi?id=217076#c7 suggests setting the kernel parameter acpi_mask_gpe=0x6E But I'm resistant to try it because: ``` When you specify a kernel boot parameter like acpi_mask_gpe=0x6E, you're telling the kernel to ignore or mask a specific ACPI GPE, in this case, the GPE with the address 0x6E. This can be useful in certain scenarios where a specific GPE is causing issues, like system instability or high CPU usage. By masking the GPE, you prevent the system from processing that event, which can work around the issue. However, you should only use this parameter if you are sure that the specific GPE is causing issues and you understand the implications of masking it. In some cases, it can lead to other problems, like certain hardware events not being correctly detected by the OS. ``` - Chat GPT 4 -- 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/1987829 Title: LG Gram 12gen high CPU use when USB-C/TB is in use Status in linux package in Ubuntu: Confirmed Status in linux package in Fedora: New Bug description: LG Gram laptop 17Z90Q with a Core i7-1260P CPU.

[Kernel-packages] [Bug 1987829] Re: LG Gram 12gen high CPU use when USB-C/TB is in use
Hello everyone, I have been following this thread for a while now, but have not yet seen others report the same thing I am experiencing. I am using an LG Gram 14Z90Q-G.AA76B and have experienced high CPU usage from kworker threads on every distro I have tried (Fedora, ArchLinux, VanillaOS, Ubuntu). >From my experience, there is a somewhat reliable way to temporarily stop the high CPU usage. I don't dualboot windows, so I cannot test the suggestion of booting from windows to linux. Rather, I have noticed the following pattern: 1. Plug In USB-C cable (charging/HDMI) 2. Run "top" to verify that 3 kworker threads appear with high CPU usage. The fan will eventually kick in 3. Suspend the laptop (close the lid, press power button, press Fn+s, or manually suspend) and wait for the fan to completely turn off. Optionally unplug and plug in USB-C cable (sometimes helps). 4. Wake device from sleep. 5. Run "top" again, kworkers will be gone Now this does not work 100% of the time, as sometimes after waking from sleep the device still keeps the kworker threads up and running, but eventually after doing this they disappear until the next reboot. This workaround gets the job done for me, as long as I don't have to reboot often. Will share these findings on the bugzilla site as well.

I'm experiencing this problem on an LG 14ZD90Q with Ubuntu 22.10, latest packages and kernel from the default repos. Mostly the problem occurs when the charger is plugged in, but today it also happened for a while when I had no USB-C devices connected. (I was using a couple of USB-A devices, a keyboard and mouse.) I found a mitigation: disable Intel Turbo Boost, per https://www.tautvidas.com/blog/2011/04/disabling-intel- turbo-boost/ (tl;dr: echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo as root.) It's not a fix, the CPU still keeps maxing out for no reason, but at least it doesn't overheat or max out the fan anymore. Might be useful while we wait for a kernel fix that stops this triggering in the first place. -- 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/1987829 Title: LG Gram 12gen high CPU use when USB-C/TB is in use Status in linux package in Ubuntu: Confirmed Status in linux package in Fedora: New Bug description: LG Gram laptop 17Z90Q with a Core i7-1260P CPU.

Re: [Kernel-packages] [Bug 1987829] Re: LG Gram 12gen high CPU use when USB-C/TB is in use
I am running LG Gram 16Z90Q (Intel I5) with PopOS and kernel 6.0.6 and I don't have this issue. Battery lasts half a day, it does not get hot whether plugged in or not. I had stability issues with Ubuntu, although I was running the newest release, not the LTS version and I did not have much time to dig into what is causing it. Then I figured System76 guys are building OS for laptops so maybe they already did the necessary tricks. And I fell in love with their tiling windows manager. The only things that do not work are fingerprint reader and the screen brightness buttons (they work with huge lag). śr., 22 lut 2023 o 01:55 Kai-Heng Feng <1987...@bugs.launchpad.net> napisał(a): > Please give latest mainline kernel a try: > https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2/amd64/ > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1987829 > > Title: > LG Gram 12gen high CPU use when USB-C/TB is in use > > Status in linux package in Ubuntu: > Confirmed > Status in linux package in Fedora: > New > > Bug description: > LG Gram laptop 17Z90Q with a Core i7-1260P CPU. > > Whenever an external monitor is connected to USB-C/Thunderbolt 4, > average load goes above 3.0 and the machine is getting very hot. > > Output from top -H shows a lot of kworker CPU usage: > > top - 11:45:06 up 33 min, 2 users, load average: 3,30, 3,08, 2,79 > Threads: 1442 total, 2 running, 1440 sleeping, 0 stopped, 0 zombie > %Cpu(s): 0,1 us, 3,7 sy, 0,0 ni, 96,1 id, 0,0 wa, 0,0 hi, 0,1 si, > 0,0 st > MiB Mem : 15684,6 total, 8510,2 free, 2580,8 used, 4593,6 > buff/cache > MiB Swap: 3815,0 total, 3815,0 free, 0,0 used. 11326,9 avail > Mem > > PID USER PR NIVIRTRESSHR S %CPU %MEM TIME+ > WCHAN COMMAND > 7766 root 20 0 0 0 0 R 19,8 0,0 0:56.05 > worker_th+ kworker/0:2-events > 196 root 20 0 0 0 0 D 15,8 0,0 1:18.12 > ec_guard kworker/u32:2+USBC000:00-con0 > 10237 root 20 0 0 0 0 I 12,9 0,0 0:26.44 > worker_th+ kworker/0:0-events > 1027 root 20 0 0 0 0 I 6,6 0,0 0:43.30 > worker_th+ kworker/1:3-events > 10971 root 20 0 0 0 0 I 4,0 0,0 0:00.20 > worker_th+ kworker/15:0-events > 175 root 20 0 0 0 0 I 2,3 0,0 0:03.24 > worker_th+ kworker/11:1-events > 2410 root 20 0 0 0 0 I 1,7 0,0 0:05.49 > worker_th+ kworker/9:3-events > > Perf shows a lot of time spent inside > handle_irq_event/acpi_ev_gpe_detect/acpi_hw_gpe_read. > > Additionally, kernel log is getting spammed with these lines every 4 > seconds (but also without any USB-C device attached): > > [ 223.514304] ACPI Error: No handler for Region [XIN1] > (f2ad4f1f) [UserDefinedRegion] (20210730/evregion-130) > [ 223.514323] ACPI Error: Region UserDefinedRegion (ID=143) has no > handler (20210730/exfldio-261) > > [ 223.514337] > Initialized Local Variables for Method [_TMP]: > [ 223.514339] Local0: 21495082Integer > 0034 > > [ 223.514349] No Arguments are initialized for method [_TMP] > > [ 223.514354] ACPI Error: Aborting method > \_SB.PC00.LPCB.LGEC.SEN2._TMP due to previous error (AE_NOT_EXIST) > (20210730/psparse-529) > > ProblemType: Bug > DistroRelease: Ubuntu 22.04 > Package: linux-image-5.15.0-46-generic 5.15.0-46.49 > ProcVersionSignature: Ubuntu 5.15.0-46.49-generic 5.15.39 > Uname: Linux 5.15.0-46-generic x86_64 > ApportVersion: 2.20.11-0ubuntu82.1 > Architecture: amd64 > AudioDevicesInUse: >USERPID ACCESS COMMAND >/dev/snd/controlC0: me 1678 F pulseaudio >/dev/snd/controlC1: me 1678 F pulseaudio > CRDA: N/A > CasperMD5CheckResult: pass > Date: Fri Aug 26 11:57:05 2022 > InstallationDate: Installed on 2022-08-25 (1 days ago) > InstallationMedia: Ubuntu 22.04.1 LTS "Jammy Jellyfish" - Release amd64 > (20220809.1) > MachineType: LG Electronics 17Z90Q-G.AA78N > ProcFB: 0 i915drmfb > ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.15.0-46-generic > root=UUID=e2f96916-a67c-432e-b687-730071271216 ro quiet splash vt.handoff=7 > PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No > PulseAudio daemon running, or not running as session daemon. > RelatedPackageVersions: >linux-restricted-modules-5.15.0-46-generic N/A >linux-backports-modules-5.15.0-46-generic N/A >linux-firmware > 20220329.git681281e4-0ubuntu3.4 > SourcePackage: linux > UpgradeStatus: No upgrade log present (probably fresh install) > dmi.bios.date: 07/06/2022 > dmi.bios.release: 0.1 > dmi.bios.vendor: Phoenix Technologies Ltd. > dmi.bios.version: A1ZG0380 X64 > dmi.board.asset.tag: Base Board Asset Tag > dmi.board.name: 17

[Kernel-packages] [Bug 1987829] Re: LG Gram 12gen high CPU use when USB-C/TB is in use
I've also noticed high CPU usage on an LG Gram 17Z90Q, with a Core i7-1260P CPU, when plugging in the USB-C charger. I checked on the CPU usage using `top`. If I unplug the charger, the kworker processes causing the CPU usage disappear within about 2 seconds, and about 10 seconds later the system will have cooled enough for the fan to start spinning down. If I plug the charger back in, the kworker processes reappear almost instantly, and about 15 seconds later the fan starts to spin up again. For me, the kworker processes and fan noise remain even when the battery is at 100% charge, so long as it remains plugged in. A few of the kworker process commands taking up the most CPU (when plugged in): kworker/u32:15+USBC000:00-con0 kworker/0:1+kacpi_notify kworker/u32:2-events_power_efficient kworker/0:0-events kworker/1:2+kec_query kworker/0:3-events kworker/15:2-events The system runs fine on battery, remaining cool and quiet. -- 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/1987829 Title: LG Gram 12gen high CPU use when USB-C/TB is in use Status in linux package in Ubuntu: Confirmed Status in linux package in Fedora: New Bug description: LG Gram laptop 17Z90Q with a Core i7-1260P CPU.

I can confirm that the overheating issue happens on a LG Gram 14 14ZB90Q with an i7 1260P whenever I plug it into its power adapter. Also when rebooting I get "Failed to start Detect the available GPUs and deal with any system changes." message and have to power off before powering it back on to boot it correctly. I also get the spam of ACPI messages "ACPI Error: Aborting method \_SB.PC00.LPCB.LGEC.SEN2._TMP" If I power it off, and leave it off for a bit, then power up just on battery the temps seem normal. But when plugging into the power adapter, it will act normal for a couple minutes, then suddenly it gets really hot, even though cpu usage is minimal, and clock speeds are low.
