Right, commit 6c5151a9ffa9f796f2d707617cecb6b6b241dff8
("ath10k: batch htt tx/rx completions")
is very suspicious.
Please revert it.
BTW, ath10k_htt_txrx_compl_task() runs from softirq context, so the
_bh() prefixes are not really needed.
It seems lot of batching happens in wifi drivers, not necessarily at the
right places.
