I cannot tell what this firmware message is about because it is undocumented. The response code decodes to MAC_CONF_GROUP (0x3) and sub-command 0xfd, which is not listed in the firmware API header file: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git/tree/drivers/net/wireless/intel/iwlwifi/fw/api/mac-cfg.h#n76 0xfd is located in the range between PROBE_RESPONSE_DATA_NOTIF and CHANNEL_SWITCH_START_NOTIF. So it is likely some other xxx_NOTIF event. Without further information the best we could do is ignore the event. But I will try to ask Linux developers for clues first. > Dec 20 13:52:30 lenny /bsd: iwm0: fatal firmware error Could you enable 'ifconfig iwx0 debug' and trigger this firmware error again to get more details about the error?
