[Kernel-packages] [Bug 887793] Re: [HP 6710b] Kworker constantly taking about 100% CPU
Tried to read all.. but I think I have different info. I originally got the 100%CPU on kube and ended up disabling and not starting any of that, but the 100% CPU started on another process.. just one, so removed and rebooted.. and again it's not on gnome-shell.. however found the cpulimit and set gnome-shell to 30 or 40%. It functions now if I don't open too many windows. (or open a browser with too many by mistake and manage to get ctrl-alt F2 fast enough to log in and kill it, which usually unfreezes X. I did buy a 1300Mb wifi a while back, and no support for linux, so I dug up the firmware (dual channel, so 2) and added.. seemed ok for weeks, but that's when KUBE stuff started chowing down on my CPU. I'm not good/familiar with this whole bug thing and my time is super valuable right now, so Please just say if I do something wrong or need to add info. Also, some mention 20.04, but I've been on 18.04 LTS over 6 months now. Plus some issues with the firmwares, I have multiple RTL chips. from, prolly 14 years ago now, to the two new ones in the dual band ethernet card. One other I'm pretty sure is in unused 2 SATA RAID onboard (14 yr old) Dunno, happy to provide more info but my time is worth to much right now to not clean install in a couple days if it's not fixed. I can't work with 6 windows.. often over 130 win/tabs and close to 200 on Win 7.1.. but then it gets slow and warning, now.. an extra window and I better get to ctrl-alt-F2 quick or hard boot. Let me know. I hope it tells me if there's replies.. (will look a bit) might try pull the wifi.. but wanted to do some stuff.. but have much more critical todo anyway.

[Kernel-packages] [Bug 887793] Re: [HP 6710b] Kworker constantly taking about 100% CPU
For anyone finding this the problem has re-appeared with Ubuntu 20.04 on a Fujitsu Lifebook A544 after upgrading to BIOS version 1.24 (or 1.25). It shows itself as workers kacpid and acpid_notify hogging most of a core. the fix (or workaround?) is to run sudo sh -c 'echo "disable" > /sys/firmware/acpi/interrupts/gpe13' which works until a reboot, or to make it persistent add to the root crontab (using sudo crontab -e) @reboot echo "disable" > /sys/firmware/acpi/interrupts/gpe13 Whether this has any side effects I don't know. -- 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/887793 Title: [HP 6710b] Kworker constantly taking about 100% CPU Status in linux package in Ubuntu: Confirmed Bug description: I've this issue since the latest Ubuntu 11.10 version, all updates applied till today, and it's still there.

[Kernel-packages] [Bug 887793] Re: [HP 6710b] Kworker constantly taking about 100% CPU
I have just performed a clean install of Ubuntu 14.10 on a Samsung Chronus 7 (700Z7C-S02UK), and this problem returned. This time, adding acpi=noirq to GRUB_CMDLINE_LINUX_DEFAULT did not solve the issue (as it did with Ubuntu 14.04). Instead, as mentioned in posts above, disabling GPE13 works. I have added an entry to my /etc/rc.local so this is performed on startup: echo disable /sys/firmware/acpi/interrupts/gpe13 I've had a read of what was discussed on the kernel thread here: https://bugzilla.kernel.org/show_bug.cgi?id=53071 and it looks like this may not be a bug, but rather a manufacturer incompatibility. -- 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/887793 Title: [HP 6710b] Kworker constantly taking about 100% CPU Status in “linux” package in Ubuntu: Invalid Bug description: I've this issue since the latest Ubuntu 11.10 version, all updates applied till today, and it's still there.
