CONFIG_ATH10K_TRACING=y

trace-cmd record -e ath10k:ath10k_log_err -e ath10k:ath10k_log_warn -e
ath10k:ath10k_log_info -e ath10k:ath10k_log_dbg -e
ath10k:ath10k_wmi_cmd -e ath10k:ath10k_wmi_event -e
ath10k:ath10k_htt_stats -e ath10k:ath10k_wmi_dbglog

(this excludes the ath10k:ath10k_log_dbg_dump)

If it's too big to attach/paste the trace.dat file then a reasonable
output of backlog from `trace-cmd report` before FW crashes might
suffice. Considering your other mail this may prevent the bug from
appearing though.
