Comment 5 for bug 1991036

I think kernel team needs patch sent to ML, but I don't do a lot of kernel stuff. FWIW, here's the log from 6.1-rc5 which includes the fix:

(You can see I try the unpublished firmware from the ath11-firmware repo right now and it doesn't help either).

(but anything is better than hanging netlink and requiring you to reboot via sysrq ;))
