Attached log file contains reproduce method and the crash backtraces in detail. quote from Bjoern: "I would suggest you can go and start debugging the code path from the call from LinuxKPI to mo_ampdu_action -> iwlwifi -> downcall into the firmware and see if you find the problem that makes the firmware "stall"." quote of the firmware error messages: iwlwifi0: lkpi_ic_ampdu_rx_start: mo_ampdu_action returned -60. ni 0xfffffe00bdfbb000 rap 0xfffffe00bdfbbd58 iwlwifi0: HCMD_ACTIVE already clear for command UNKNOWN iwlwifi0: No beacon heard and the session protection is over already... iwlwifi0: linuxkpi_ieee80211_connection_loss: vif 0xfffffe00bdf1fc80 vap 0xfffffe00bdf1f010 state RUN iwlwifi0: Failed to send flush command (-5) iwlwifi0: flush request fail iwlwifi0: Couldn't send the SESSION_PROTECTION_CMD WARNING trans->state != IWL_TRANS_FW_ALIVE failed at /usr/src/sys/contrib/dev/iwlwifi/iwl-trans.h:1446 iwlwifi0: iwl_trans_wait_txq_empty bad state = 0 iwlwifi0: Failed to trigger RX queues sync (-5) iwlwifi0: Failed to synchronize multicast groups update iwlwifi0: Failed to send MAC_CONFIG_CMD (action:2): -5 iwlwifi0: failed to update MAC 0xfffffe00bdf1fc9eM iwlwifi0: Failed to send flush command (-5) iwlwifi0: Failed to send MAC_CONFIG_CMD (action:2): -5 iwlwifi0: failed to update MAC 0xfffffe00bdf1fc9eM iwlwifi0: Failed to send LINK_CONFIG_CMD (action:2): -5 iwlwifi0: PHY ctxt cmd error. ret=-5 -- You are receiving this mail because: You are the assignee for the bug.
