With Linux kernel 6.1.1, I see this Call Trace in journal log:

Complete log: https://0x0.st/o5Wo.txt

When I saw that call trace, I thought the problem was the same as previous kernel versions, where randomly when I boot the system, the wifi just didn't work and the system was unresponsive: https://0x0.st/o5WH.txt
Or sometimes when wifi cuts off: https://0x0.st/o5W8.txt
Context problem of that issue: https://bbs.archlinux.org/viewtopic.php?id=276765 (and sorry for not mentioning that the problem was still there. They happened a few times and I ended up forgetting about it.)

But now, I don't have any problems with wifi. The system is ok, I can use it normally.
So, my question is: What's the issue? I'm trying to understand the call trace, but I can't.

LTS kernel doesn't have this issue: https://0x0.st/o5WX.txt

New warning introduced in 6.1 by https://github.com/torvalds/linux/commi … a868b70d68

Adriik · 2022-12-23 21:48:26

Thanks for the link.

So, how the link says: "This change ONLY adds a run-time warning. As false positives are currently still expected, this will not block the overflow."
I can just ignore it, right? If that the case, I'm going to mark the thread as solved.
