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: [email protected]

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@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.
