    Question What is kworker?

    I've started seeing something called "kworker" listed recently when I run top. There is no man page for it, and there seems to be no documentation at all. Searching Google didn't help.

    Even odder, it regularly makes the top ten resources consumer in top, but it doesn't seem to be using any resources:

    26 root 20 0 0 0 0 R 0 0.0 7:08.58 kworker/1:1
    What's it for, what does it do, and is there any documentation?

    Re: What is kworker?

    I was really hoping someone would answer this thread because I spent quite a while looking. You're right. There's not a lot of info out there. I see people affected with an Intel video card or a mouse, so it would seem like it has something to do with interrupts but I'm not sure. I even went to Bing and wikipedia as a last resort. It didn't help. Here's what I found in case you didn't. It's not much help.

    I'm having trouble with this as well. Running natty, so using 2.6.27-8 x86_64.

    It seems alleviated by running
    Code:
    echo disable > /sys/firmware/acpi/interrupts/gpe01
    Source.

    Kworker is what controls the ACPI wakeup signals from the BIOS.

    The latest kernel, well all of them since 2.6.35 have had issues with too many wakeups.

    This is an issue across ALL linux distributions.

    Hopefully it's going to be fixed in kernel 2.6.35.

    The current snapshot is: 2.6.37-rc7-git3 so it shouldn't be too long.

    Thank you for the description. Do you know where this is documentation on this, and other mystery tasks like the "migration" process?

    I'm using Arch with kernel 2.6.36-ARCH, and I have seven kworker processes.

    Is this better or worse than your situation?

    I have eight right now. Not sure what that signifies.
