How to fix this error No irq handler for vector

  • 772

I have done sudo do-release-upgrade from 21.10 to 22.04 Ubuntu and suddenly i get this errror when i startup my computer below:

[    0.004902] __common_interrupt:1.55 No irq handler for vector
/dev/sda2: clean, 3697434/45760512 files, 55603510/183012096 blocks

What does it mean is this a serious error or can i leave it is there someone that knows something about this error?

It came up after i upgrade Ubuntu 21.10 to 22.04? I' am curious is this serious and has to be fixed or should i leave it? My computer starts normally it is just this confusing error?

Or must it be fixed i'am confused?

  1. You are asking about:

    1. Possible causes
    2. Severity / Need for fixing

    I first noticed a similar message in my recently installed Bodhi Linux (an Ubuntu derivative), and I didn't notice anything wrong with OS functioning. As per this, for item 2 above I would say you shouldn't be concerned. It might have happened to me in other systems, and I simply didn't notice it.

    In this long thread it is reported that updating the BIOS made the message disappear, e.g. this. Also, disabling IOMMU in the BIOS helped some, e.g. this (but for others this didn't work).

    As for item 1, the error seems to arise when a multiple CPU cores are initialized (ref), but it's possibly safe to ignore (ref).

    I suggest you try disabling IOMMU in the BIOS if possible, and post feedback. Also, please post:

    1. The complete model of your PC, and motherboard.
    2. Output of uname -a.
