--- Comment #2 from Shirkdog <msh...@daemon-security.com> --- (In reply to Bjoern A. Zeeb from comment #1) >>>>>So you left the laptop over night and then you typed in ifconfig wlan0 >>>>>down and that immediately led to what's below in the log? After a period of time, I come back and wlan0 has lost carrier with the wireless network, I will see "no carrier" under "status" when I do "ifconfig wlan0". When I do a netif restart or "ifconfig wlan0 down" or anything with the interface that is when the kernel will panic. >>>>Now it will not come up by itself if this was a manual ifconfig down or >>>>netif stop. So something else happened that very second or the crash was >>>>not produced by manual intervention. When I see the wlan0 interface is no longer connected to the network, everything else related to the OS or kernel are fine. >>>>>Did you by any chance run a netif wlan0 restart (not stop) or something >>>>>else happened in parallel? Do you have wpa logs for that time (ideally >>>>>let it log to console as well so we have a chance to see -- and remove >>>>>sensitive information). I typically would do "service netif restart" and not specifically for wlan0. I will get wpa_supplicant setup so I will have more detailed logs. The only thing I see before I try to "service netif restart" is the following in /var/log/messages: Jan 21 08:45:58 15-CURRENT-HOST kernel: ---<<BOOT>>--- BEFORE THIS ENTRY system booted up, these are the first logs seen regarding wireless Jan 21 09:25:05 15-CURRENT-HOST kernel: [2373] iwlwifi0: linuxkpi_ieee80211_beacon_loss: vif 0xfffffe0143dfbe80 vap 0xfffffe0143dfb010 state RUN Jan 21 09:25:05 15-CURRENT-HOST syslogd: last message repeated 1 times Jan 21 09:25:05 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: CTRL-EVENT-DISCONNECTED bssid=BSSID-MAC reason=0 Jan 21 09:25:05 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Added BSSID BSSID-MAC into ignore list, ignoring for 10 seconds Jan 21 09:25:05 15-CURRENT-HOST kernel: [2373] wlan0: link state changed to DOWN Jan 21 09:25:06 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Trying to associate with BSSID-MAC-2 (SSID='AWESOME-SSID-NAME' freq=2417 MHz) Jan 21 09:25:06 15-CURRENT-HOST wpa_supplicant[75193]: FT: Invalid key management type (2) Jan 21 09:25:06 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Associated with BSSID-MAC-2 Jan 21 09:25:06 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: WPA: Key negotiation completed with BSSID-MAC-2 [PTK=CCMP GTK=CCMP] Jan 21 09:25:06 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: CTRL-EVENT-CONNECTED - Connection to BSSID-MAC-2 completed [id=2 id_str=] Jan 21 09:25:06 15-CURRENT-HOST kernel: [2374] wlan0: link state changed to UP Jan 21 09:25:06 15-CURRENT-HOST dhclient[15178]: New IP Address (wlan0): 192.168.1.112 Jan 21 09:25:06 15-CURRENT-HOST dhclient[16695]: New Subnet Mask (wlan0): 255.255.255.0 Jan 21 09:25:06 15-CURRENT-HOST dhclient[17849]: New Broadcast Address (wlan0): 192.168.1.255 Jan 21 09:25:06 15-CURRENT-HOST dhclient[18673]: New Routers (wlan0): 192.168.1.1 Jan 21 12:50:56 15-CURRENT-HOST kernel: [14724] iwlwifi0: linuxkpi_ieee80211_beacon_loss: vif 0xfffffe0143dfbe80 vap 0xfffffe0143dfb010 state RUN Jan 21 12:51:01 15-CURRENT-HOST kernel: [14729] iwlwifi0: linuxkpi_ieee80211_beacon_loss: vif 0xfffffe0143dfbe80 vap 0xfffffe0143dfb010 state RUN Jan 21 12:51:01 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: CTRL-EVENT-DISCONNECTED bssid=BSSID-MAC-2 reason=0 Jan 21 12:51:01 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Removed BSSID BSSID-MAC from ignore list (expired) Jan 21 12:51:01 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Added BSSID BSSID-MAC-2 into ignore list, ignoring for 10 seconds Jan 21 12:51:01 15-CURRENT-HOST wpa_supplicant[75193]: ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Can't assign requested address Jan 21 12:51:01 15-CURRENT-HOST kernel: [14729] iwlwifi0: linuxkpi_ieee80211_connection_loss: vif 0xfffffe0143dfbe80 vap 0xfffffe0143dfb010 state RUN Jan 21 12:51:01 15-CURRENT-HOST kernel: [14729] wlan0: link state changed to DOWN Jan 21 12:51:01 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Removed BSSID BSSID-MAC-2 from ignore list (clear) Jan 21 12:51:12 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Trying to associate with BSSID-MAC-3 (SSID='AWESOME-SSID-NAME' freq=2417 MHz) Jan 21 12:51:12 15-CURRENT-HOST wpa_supplicant[75193]: FT: Invalid key management type (2) Jan 21 12:51:12 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: Associated with BSSID-MAC-3 Jan 21 12:51:12 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: WPA: Key negotiation completed with BSSID-MAC-3 [PTK=CCMP GTK=CCMP] Jan 21 12:51:12 15-CURRENT-HOST wpa_supplicant[75193]: wlan0: CTRL-EVENT-CONNECTED - Connection to BSSID-MAC-3 completed [id=2 id_str=] Jan 21 12:51:12 15-CURRENT-HOST kernel: [14740] wlan0: link state changed to UP This IP is picked up from DHCPD running on a bridge interface I use for running bhyve VMs, the wireless connection is gone and wlan0 picks this up from localhost: Jan 21 12:51:13 15-CURRENT-HOST dhclient[40302]: New IP Address (wlan0): 172.16.66.142 Jan 21 12:51:13 15-CURRENT-HOST dhclient[42209]: New Subnet Mask (wlan0): 255.255.255.0 Jan 21 12:51:13 15-CURRENT-HOST dhclient[43952]: New Broadcast Address (wlan0): 172.16.66.255 Jan 21 12:51:13 15-CURRENT-HOST dhclient[46038]: New Routers (wlan0): 172.16.66.6 When I see the wireless is not working, I do "service netif restart" and these are the logs that follow.
