What kernel version do you have this issue? Last known good version?

This is an openwrt gateway device on x86_64 platform. I'm not sure the exact version number that came up, it seems like 6.1.27 was not encountered before. I have encountered it since kernel 6.1.32, but it is also from this version that I have relatively large IPv6 udp traffic, conntrack -L|grep -c udp shows that the number is between 600 - 2000.

Thank you for your prompt attention, I have just submitted additional information. And the attachment is the log of system.

Can you reproduce this regression on latest mainline?

Sorry, I may not be able to adapt openwrt to the mainline version in a short time.
But this problem is only encountered on openwrt as a gateway.

The same warning has been triggered on 4.14, 5.15, 6.1 and 6.4-rc kernels on syzbot (https://syzkaller.appspot.com/bug?extid=de6565462ab540f50e47). The provided reproducers (such as https://syzkaller.appspot.com/text?tag=ReproC&x=15a10e8aa80000) are reproducing the same warnings on multicore (at least 2 CPUs) qemu instance.

I've reproduced the issue on ccff6d117d8dc8 (v6.5-rc2) and 1c59d383390f9 (mainline/master).
