The same problem also happens on Intel Centrino Ultimate-N 6300.  I'll attach a
dmesg output later.

dmesg printout

Hi all,

I am new to freebsd, thank you for a wonderful system!

I keep getting iwn controller panic while booting.
Eventually the machine does come up and does connect to the wireless network.
But it takes quite long to boot and has most of the time one, sometimes up to 4
rounds of iwn controller panic. Sometimes, but rarely, it does not panic.

The relevant lines from rc.conf around the panic are below and I attach dmesg,
rc.conf and loader.conf

The panic might have something to do with dhcp since I do not get it when I use
dhclient after boot.

Thank you in advance for all tips

Best regards

Markus

** my system

I am on a Lenovo SL520 Laptop
the wlan is identified as
iwn0:  mem 0xf220-0xf2201fff irq 19 at
device 0.0 on pci3

uname -a
FreeBSD ## 11.0-RELEASE-p2 FreeBSD 11.0-RELEASE-p2 #0: Mon Oct 24
06:55:27 UTC 2016
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

freebsd-version
11.0-RELEASE-p3

** when does the panic show up

I only get this error when booting.
I cannot remember having seen this panic when I delete the DHCP from
ifconfig_wlan0="WPA DHCP" and use dhclient later.
When I play around manually, I never get the panic.

Oddly. when I use SYNDHCP instead of DHCP I get an errormessage while booting
about some wrong pararameter, but *no panic either*.
This errormessage flashes by, to fast to read, and does not show up in either
dmesg or messages.

Putting
if_iwn_load="YES"
iwn1000fw_load="YES"
into loader.conf, does not change anything except reporting "module iwn already
present!" in line 9 of dmesg.
The result without the two lines is the same.

btw
The wlan worked fine when I had PC-BSD 10.3 on the Laptop for a couple of
weeks, but being new to BSD maybe I just didn't notice.
