error with i2c, what could be the reason? other kernels have the same error.

Please use [code][/code] tags. Edit your post in this regard.

It might help to know what i2c-9 and i2c-10 are, please post the entire dmesg (or system journal), no just isolated error messages.
Do you also experience any symptoms (missing devices etc)?

i2c is essentially a router, it works like a bus, SMBus is built on i2c, it connects, detects, and controls devices, and as for devices, basically everything works except that I don't use it yet or don't know, but the driver is important and it would be nice to fix it.

Is that explanation from SquatGPT?
SMBus is an i2c derivate, not "built on it".

And that still leaves us at "Fix *what*?"
It's still not clear whether or what any problem is here.
You've posted some disconnected kernel/module messages from some undisclosed hardware.

Maybe try your luck at lkml…

I don't know why you're responding so aggressively or if I asked a stupid question, but I answered what i2c does, and I'm attaching a link to this module. https://www.kernel.org/doc/html/latest/i2c/index.html where else is it better described for what it is needed, about i2c-9 ic-10 it is simply not carrying any information at all, but it is unlikely that you will help with this problem considering how You're talking aggressively, considering that I asked for help, and about the core logs, well, that's actually the whole i2c log. There's nothing else from it. I don't even know what you want me to add.

I'm not aggressive and I didn't ask what i2c does, so I don't understand why you felt like posting what very much sounds something ChatGPT told you.
The open question still remains what your "problem" actually is.
Whether it's just some spurious messages in your journal because the bus is probing non-existing channels or there's an actual impact: something that doesn't work and that you maybe relate to those messages.

I don't even know what you want me to add

Post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

1. same w/ the non-cachyos kernel or lts kernel?
==>>> 2. is there a parallel windows installation? <<====
3. do webcam, touchpad and keyboard work? Is there any indication on your side that this isn't just noise from the controller?

1. yes, there is a nearby windows
2. on any core, such a log
3. I don't know, I have a relatively new device and something may not work, for example, I made a patch in the kernel because there was no driver for the microphone to work, and now I'm trying to make the microphone indicator work, I don't know if i2c SMBus can control this, but still, well, in general, nothing that doesn't work for I'm not there, at least not from what I use.
4. I don't know, but the error doesn't look like something that can be ignored, especially because it's SMBus and it's clearly a problem with some devices, I also tried to look through i2detect -y 9,10,11 and only at 11 there was some information, it looks like the problem is in the 9-10 device, but the strangest thing is that they are almost identical except for with the exception of the address, I attach the information
