Log spammed with "kernel: i2c i2c-2: sendbytes: NAK bailout."

[in_trauma]

Not sure what this is or if it's a concern but my logs spammed with this a few times a minute. Nothing else in the logs of note. No warnings, no errors.

The only post I could find with similar message on unraid mentioned C states of SSDs but doesn't really make sense to me?

You need to post your diagnostics to put it all into perspective for whomever is capable of helping.

This happened to me as well but only when the network gets disconnected after boot. Reconnecting the network doesn't fix the issue, however rebooting with the network correctly plugged in will prevent the errors from showing in the logs.

 

I've been having issues recently on 6.12.7 and 6.12.8 with Unraid crashing when the network gets disconnected (ie. router rebooting), so I was doing some tests (but wasn't able to reproduce sadly). Not sure any of these kernel errors are related to the crash issues but that's my only lead for now.

 

It's probably important to note that I'm using IEEE 802.3ad dynamic link bonding over 2 interfaces (LACP) and it only happens when connection to both interfaces is lost simultaneously.
