I think I was affected by a similar issue - the "ctstoself" function at least. I was not able to draw any useful conclusion.

@ynezz ynezz added bug issue report with a confirmed bug target/mediatek pull request/issue for mediatek target kernel pull request/issue with Linux kernel related changes labels Mar 23, 2022

Can you try to disable the 2.4 ghz interface and let me know if this happens again? How much time does it take to happen in your scenario?

Can you try to disable the 2.4 ghz interface and let me know if this happens again? How much time does it take to happen in your scenario?

I can't to do that unfortunately as some clients are dependent on 2.4ghz and there's no telling when I may get a kernel panic as it seems to be a rare occurrence.

How much time does it take to happen in your scenario?

From what I can tell its quite rare, on this specific router I've had an uptime of roughly 2 weeks before randomly having the router crash. It's the first time it had a kernel panic with the issue above.
