[Kernel-packages] [Bug 1799235] Re: kworker process starts at 85% of cpu and stays there

Hi again: So, I tried both with restored default bios settings and default factory setting. The kworker process is still going at over 85%. I can turn it off w/ echo "disable" > /sys/firmware/acpi/interrupts/gpe6F in both cases. One odd thing I noticed. With the default settings, I have two

Hmm, I think the main bios change is that I have safe mode turned off (at least in part because of that unsigned module). I'll see what I can do the next time I restart the system. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in

Thanks Kai-Heng. Unfortunately, my system wouldn't boot with v4.13. I installed the following kernel-related files: linux-headers-4.13.16-041316_4.13.16-041316.201711240901_all.deb linux-headers-4.13.16-041316-generic_4.13.16-041316.201711240901_amd64.deb

[Kernel-packages] [Bug 1799235] Re: kworker process starts at 85% of cpu and stays there

I've now tested with 4.19-rc8. The kworker process remains at about 65% continuously. Not quite sure how to mark this as confirmed, but will try. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel

I should add that I issued the following last night: echo "enable" > /sys/firmware/acpi/interrupts/gpe6F And then tried to shut down my system. After 8 minutes, the system had not shut down, so I did so manually. Either the interrupts from the bug are preventing the shutdown or this is a

[Kernel-packages] [Bug 1799235] Re: kworker process starts at 85% of cpu and stays there

The issue began after a fresh system install on a new computer. Admittedly, the first system I installed was Qubes, with Fedora (24 I believe). When I decided Qubes wasn't adequate for my needs, I wiped the system (reformatted using gparted) and installed the latest Ubuntu (as of a month ago).
