kernel stack trace
A friend (Jeff Anton) reported a kernel crash when trying to configure a vlan
on a wlan interface under 13.0. I did some testing with a spare amd64 box and
was able to reproduce the crash with both 13.1-RC4 and 12.3-RELEASE-p5.
The rc.conf from my test setup looks like this:
hostname="test.alameda.xse.com"
sshd_enable="YES"
dumpdev="AUTO"
keymap="us.ctrl"
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"
vlans_wlan0="vlan0"
create_args_vlan0="vlan 1234"
wpa_supplicant="YES"
(This assumes a valid wpa_supplicant.conf.)
After booting and successfully joining wifi issuing:
ifconfig vlan0 192.168.1.1
results in a "page fault while in kernel mode" panic. Kernel stack trace
attached (13.1-RC4).
