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?
