Disabling IRQ after recent update.

English Hardware
1

Ever since an update about a week ago, I have noticed a little message pops up that it is disabling IRQ 16.
Can anyone help me solve this?

Here’s my dmesg output. It finishes booting. Then a while later shows this irq 16: nobody cared. I have “irqpoll” set as a boot option, and it made no change.

And, here is what us using IRQ 16.
16: 0 0 655 0 0 0 0 99690 0 0 0 0 0 0 0 0 IR-IO-APIC 16-fasteoi i801_smbus, snd_hda_intel:card0

thank you for any help.

The last two lines of you message, from which command is that the output? (Always good to use code tags around your paste and to include the command)

This thread discusses i801, maybe it has some suggestion that can help?

Possibly the same as this: https://bugzilla.opensuse.org/show_bug.cgi?id=1192194

“might be a stray irq after de-registering the HD-audio controller irq”

Try to set up sound cards.

  1. Builtin Realtek ALC 4080.
  2. HDMI/DP/USB-C audio output.

Thanks, I do have a suspicion it’s the sound… I’ve had issues w/ that since install, since this is (or was) such a new chipset. But, audio works. (The issues I had were w/ the ports… like plugging something into the front jack didn’t detect it as headphones). The other option is the motherboard sensors, which is that i801 device. But all my sensors appear to be working fine, too. I’m not actually sure how to change the sound driver, etc… But I will start searching. (Been using opensuse for over 10 years, but am usually lucky w/ hardware just working… Only ever had to mess w/ graphics)
