>Description:
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:
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"
And /etc/wpa_supplicant.conf has the appropriate settings for some access
points :
network={
ssid="myssid"
psk=myasciikey
}
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
firmware error log:
error type = "SYSASSERT" (0x00000005)

tx ring 18: qid=18 cur=0 queued=0
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 ?

At every boot or netif start
