i2c errors after messing around with openRGB dependencies

Previous thread describing the “messing”: https://forums.opensuse.org/showthread.php/556534-Asus-Aura-and-OpenRGB-not-working

I’ve removed it (it was the bling temptation I’m vulnerable to sometimes) some time ago but I notice some i2c related errors during boot:

    1.758482]# dmesg | grep i2c

Larger parts of dmesg related to the issue AFAICS:

Apparently there’s no impact on the system, however I’d like to fix this if possible, as there errors where not there before the “messing”.

Thanks,

Looking through this Leap 15.3 machine’s Journal, there are the following ‘i2c’ «I2C or IIC» entries indicating an error:

It seems that, an error occurred on the 1st of October but, I can’t recall if, there was any noticeable effect …

  • This error occurred only once …

Hi, dcurtisfra.

That seems to be another issue, mine is with the transfer and timeout failures, probably having to do with me modprobing what shouldn’t be modprobing, but I have no idea how to fix it. It is not a big problem, however.

The I2C bus is often fairly slow – only 100 kbit/s in Standard mode (Sm) …

  • It could be that, one of the devices attached to your Mainboard isn’t behaving properly – for example, it could be an “intelligent” Fan beginning to misbehave …
