Public bug reported:

1) Ubuntu 11.10 x64 Server (Kernel 3.0.0.14)
2) network-manager 0.9.1.90-0ubuntu5
3) A working AccessPoint, so I could connect to it with other wifi devices.
4) An AP that gets turned on, then crashes directly, gets re-enabled again and crashes again. NetworkManager tries to re-enable the AP so quickly that it creates a never ending loop. When this happens the whole Desktop freezes and only a force-reboot followed by booting into recovery mode *and* doing "sudo rm -R -f /etc/NetworkManager/" makes sure this doesn't happen again on the next login.

At the moment I'm using the following setup with hostapd, which does give a working AccessPoint:
ip a a 10.0.0.1/24 dev wlan0
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
hostapd /etc/hostapd/hostapd.conf

Network card is well supported:
03:01.0 Network controller: Atheros Communications Inc. AR922X Wireless Network Adapter (rev 01)
