Description
This is a continuation of issue 1785: http://bugs.dragonflybsd.org/issue1785
I'm now running with BUS_DMA_NOWAIT as Joe Talbott told me. See attached patch.
My problem right now is when I fool around with wpa_supplicant. On a second use it panics.
zoidberg# ifconfig wlan0 create wlandev ral0 up
ral0: need multicast update callback
zoidberg# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
Trying to associate with 00:1d:7e:f0:fd:1f (SSID='moh' freq=2422 MHz)

panic
Same if I set it up in rc.conf and do a 'rcrestart netif'
The panic looks like this:
Unread portion of the kernel message buffer:
Fatal trap 12: page fault while in kernel mode
