Description Trois Six 2011-12-09 22:00:28 UTC
My network card : iwn0: <Intel(R) Centrino(R) Ultimate-N 6300> mem 0xd3300000-0xd3301fff irq 19 at device 0.0 on pci68

/etc/rc.conf contains the following:
ifconfig_wlan0="WPA DHCP"

And /etc/wpa_supplicant.conf has the appropriate settings for some access points :

When the system boots or when I start the interface with netif, I have a fatal firmware error and I can't use my card. I tried to disable the bgscan but it didn't change anything :

wlan0: Ethernet address: 00:24:d7:XX:XX:XX
iwn0: iwn_intr: fatal firmware error

  tx ring 19: qid=19 cur=0   queued=0  
  rx ring: cur=14

the link changes from DOWN to UP to DOWN.

I have seen that after every netif start I have two wpa_supplicant process ?

How-To-Repeat: At every boot or netif start

Bug confirmed under 9.0-RELEASE
iwn0: <Intel(R) Ultimate N WiFi Link 5300> mem 0xf1ffe000-0xf1ffffff irq 17 at device 0.0 on pci12

I get the exact same behavior and error messages as reported if I attempt to connect to a 5GHz ssid, however, this wireless functions correctly using a ssid over a 11g channel (2412 MHz).
