AFAICT that's a simple 'use RCU without holding rcu_read_lock' warning. I've not dug through ath10k to see who should be doing rcu_read_lock, but the few places I did look at don't seem to have changed recently.Just this morning I applied a patch which should fix this: https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath-next&id=2615e3cdbd9c0e864f5906279c952a309871d225 Please let me know if it fixes the issue.The traces are gone after applying this patch, so it does help: Tested-by: Rafael J.
