For a while I thought that the error that I noted in GL-iNet AX1800 new router - OpenWrt support? - #710 by dr-m had been magically fixed, but it seems that it can take several hours or even days between the messages. Below I’m reproducing the first stack trace from the dmesg output of my router, as well as all subsequent messages of the similar type (omitting the stack traces):

I haven’t tried applying the patch that had previously fixed the problem for me. I did find a recent change https://github.com/openwrt/openwrt/pull/18795 which might be related to this. I will upgrade and see what happens.
