Hi,
I get this warning in my C7. The router is working like a charm, is only for informational purposes.

Is it normal?
Thanks a lot,

No, a warning is never normal, but you missed to copy the most important parts of the warning.
Sorry, here comes the full warning log:

Hi,
I have updated my router to the lastest firmware version (with the same kernel version), and the warning is over.
Thanks,

Did you reinstall all your manually installed packages? Because when you sysupgrade, you loose them and have to reinstall them. Maybe your problem was caused by one of them, and now it's out of the way.
I've checked, I don't have those warnings in my logs (I do have Archer C7 too).
I did the sysupgrade and then reinstalled all the missing packages (ddns, luci-ssl, sqm...).
Now I have the same packages as before upgrading and the warning is over.
Noo!!!
Here comes again!!!

Maybe the problem is the wifi driver?
Yes I'm using SQM, but, I'd tried to disable it and the warning still appears.

I've been getting the occasional similar, but not exactly the same, kind of error.

Think I used to get something about the Ath10k, (9k?) before as well.
I'm pretty much running SQM and nothing else. Home router, cable modem in, 2.4G and 5G wifi single AP for the whole house.
Now I'm not running/installed SQM (I reflashed my router again), and the warning is still there.

Still nobody knows about this? I rebooted two weeks ago, had the same CPU warning line except for PID 0 instead of 3, and same stack and Call Trace number first line. 16 lines of addresses, rather than 10. What's that mean? Don't ask me.
Would like to know if it's truly nothing to worry about. So far, nothing noticiably wrong, except for a loss of 5ghz wifi after a round of trying different channels and power levels. That's why I rebooted.
Still just running SQM: Cake, Piece of Cake, and a few advanced settings mentioned in the instructions.
@JonP Are you using PPPoE and VLAN tagging?
In my case I'm using PPPoE and VLAN tagging (not using SQM).

Huh, thought I'd answered this....
No PPOE, just DOCSIS Cable Modem service common here in the US. And, now that I think about it I had a few of these earlier on, but much less often, on versons before 17.01.2. Seems like every boot I get one now.
I hope one day somebody could find why is happening.
Despite of that "warning" the router is working great.

I am just building a chinese device with the firmware that i built. The device seems to work fine but this error seems to be in Dmesg.
The router works fine and does not have any noticeable issues but this points to an underlying issue which might cause trouble forward in time.
