I'm the lead developer on the Astlinux project, which I might have
mentioned in a previous posting. This means that I have my hands in
many pots, so I'm not an expert in the latest Linux kernel changes... be
patient with me. Hard to keep track of 200+ individual projects.
I'm building 2.6.26.27 as I said for (amongst other things) an Alix 2D3
(GeodeLX) with EMP-8602 (AR-5413) as a test platform.
My kernel gets built with:
#
# Wireless
#
CONFIG_CFG80211=m
CONFIG_NL80211=y
CONFIG_WIRELESS_EXT=y
# CONFIG_WIRELESS_EXT_SYSFS is not set
CONFIG_MAC80211=m
#
# Rate control algorithm selection
#
CONFIG_MAC80211_RC_PID=y
CONFIG_MAC80211_RC_DEFAULT_PID=y
CONFIG_MAC80211_RC_DEFAULT="pid"
# CONFIG_MAC80211_MESH is not set
CONFIG_MAC80211_LEDS=y
# CONFIG_MAC80211_DEBUG_MENU is not set
# CONFIG_IEEE80211 is not set
CONFIG_RFKILL=m
CONFIG_RFKILL_INPUT=m
CONFIG_RFKILL_LEDS=y
# CONFIG_NET_9P is not set
I build compat-wireless-2.6.30 into /lib/modules/2.6.27.26-astlinux/kernel/... as a Kbuild.
The system also has iw-0.9.15 and hostapd-0.6.9.
All of this is fairly straightforward.
On boot, our /etc/init.d scripts do the following:
+ modprobe ath5k
ath5k phy0: Atheros AR5413 chip found (MAC: 0xa4, PHY: 0x61)
+ iw dev wlan0 interface add ap0 type managed
+ ip link set ap0 up
+ iw dev ap0 connect xxxx
command failed: Operation not supported (-95)
So doing some sanity checks by hand I get:

What am I missing?
How should I go about debugging this?
