Baochen - aside from finding a commit where stability disappears (from my last message, stability is achieved when I cherry pick "wifi: ath12k: modify ath12k_mac_op_bss_info_changed() for MLO"), is there any other debugging information I can provide? You mentioned that firmware is a likely culprit; would it help to get a dump from the ATH12K_COREDUMP feature (commit "wifi: ath12k: Add firmware coredump collection support")? If so, could you give me a hint about how to generate the dump and where to find it?
