Hi,
I'm hitting this one a lot with current -git, which is this one:
if (iwl_mvm_is_dqa_supported(mvm)) {
iwl_mvm_disable_sta_queues(mvm, vif, mvm_sta);
/*
* If pending_frames is set at this point - it must be
* driver internal logic error, since queues are empty
* and removed successuly.
* warn on it but set it to 0 anyway to avoid station
* not being removed later in the function
*/
WARN_ON(atomic_xchg(&mvm->pending_frames[sta_id], 0));
}
It's hit 4 times over the last day. The bug is probably older than the
commit that added this warning:
commit 94c3e614df2117626fccfac8f821c66e30556384

iwlwifi: mvm: fix pending frame counter calculation
but the pestering is new.
