This is a T61p 6459 laptop with (from pciconf -lv):
iwn0@pci0:3:0:0: class=0x028000 card=0x11108086 chip=0x42308086 rev=0x61 hdr=0x00
vendor = 'Intel Corporation'
device = 'PRO/Wireless 4965 AG or AGN [Kedron] Network Connection'
class = network
or (from dmesg):
iwn0: <Intel Wireless WiFi Link 4965> mem 0xdf2fe000-0xdf2fffff irq 17 at device 0.0 on pci3
I use it with
device iwn # Intel 4965/1000/5000/6000 wireless NICs.
device iwn4965fw
in the kernel.
>From time to time, and I think under some load, e.g. rsync a
partition in one windown and svn up /usr/ports in another,
I get this failure:
iwn0: iwn_intr: fatal firmware error
firmware error log:
error type = "NMI_INTERRUPT_WDG" (0x00000004)
program counter = 0x0000046C

I then have to restart the network via "/etc/rc.d/netif restart"
and it's back to normal.

I use it with wpa_supplicant:
/usr/sbin/wpa_supplicant -s -B -i wlan0 -c /etc/wpa_supplicant.conf -D bsd -P /var/run/wpa_supplicant/wlan0.pid
Please advise
Thanks
