Some more observations on that topic with the hardware shown above. ath10k_core_start() calls ath10k_wmi_wait_for_service_ready(), and later ath10k_wmi_wait_for_unified_ready(). The now *unconditional* call to ath10k_hif_send_complete_check() inside ath10k_wmi_wait_for_service_ready() makes the later call to ath10k_wmi_wait_for_unified_ready() fail. If I call and handle wait_for_completion_timeout() first (as it was before the patch), ath10k_hif_send_complete_check() is *not* called, and both ath10k_wmi_wait_for_service_ready() and ath10k_wmi_wait_for_unified_ready() succeed. Everything is back to normal. Side note: ath10k_wmi_wait_for_service_ready() succeeds in both cases with time_left == WMI_SERVICE_READY_TIMEOUT_HZ. #regzbot monitor: https://bugzilla.kernel.org/show_bug.cgi?id=220671
