Hi,
Board: nanopi neo, running xenial ubuntu server from: http://www.armbian.com/donate/?f=Armbian_5.20_Nanopineo_Ubuntu_xenial_3.4.112.7z
I am trying to enable the hostapd for nanopi neo, on
Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter
The default drivers
cocam@nanopineo:~$ lsmod Module Size Used by rtl8192cu 61143 0 rtlwifi 45784 1 rtl8192cu rtl8192c_common 33420 1 rtl8192cu snd_usb_audio 80300 0 mac80211 358429 3 lrtlwifi,rtl8192c_common,rtl8192cu
came with 3.4.112-sun8i looks ok and my wlan0 is AP-advertised,
wlan0 Link encap:Ethernet HWaddr ec:08:6b:1d:10:20 inet addr:10.5.5.1 Bcast:10.5.5.255 Mask:255.255.255.0 inet6 addr: fe80::ee08:6bff:fe1d:1020/64 Scope:Link
As soon I connect a device to the AP I get a kernel crash:

I built against the /usr/src/linux-headers-3.4.112-sun8i kernel the rtl8192cu-fixes
and I blacklisted /etc/modprobe/blacklist.conf the old drivers, allowing the new driver.
blacklist rtl8192cu #blacklist rtl8192c_common #blacklist 8192cu
But now I cannot start the hostapd service
ifconfig
