            Bug ID: 256494
           Summary: KERNEL PANIC - WiFi - after hot spot is down FreeBSD
                    restarts
           Product: Base System
           Version: 13.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs_at_FreeBSD.org
          Reporter: vermaden_at_interia.pl

Hi.

My /etc/rc.conf settings related to network.

    hostname=w520.local
    background_dhclient=YES
    extra_netfs_types=NFS
    defaultroute_delay=3
    defaultroute_carrier_delay=3
    harvest_mask=351

I start my network connections manually with script so that is why no network
settings in /etc/rc.conf file.

My /etc/wpa_supplicant.conf WiFi network.

    eapol_version=2
    ap_scan=1
    fast_reauth=1

    network={
      ssid="vermore5"
      psk="password"
      priority=6
    }

My hardware is ThinkPad W520 from 2011 with Intel 6300 WiFi:

    # pciconf -lv
    (...)
    iwn0_at_pci0:3:0:0:        class=0x028000 rev=0x3e hdr=0x00 vendor=0x8086
device=0x4238 subvendor=0x8086 subdevice=0x1111
        vendor     = 'Intel Corporation'
        device     = 'Centrino Ultimate-N 6300'
        class      = network



Steps to reproduce:

1. Connect to your hot spot WiFi:
    # wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -s -B
    # dhclient wlan0

2. You have Internet connection as usual - everything works.

3. Power off the hot spot WiFi (so it will not be accessible)

4. FreeBSD panics and reboots.



Hope that helps.

Regards.
