hmm... OT: who old is your hostapd version? As far as I can tell AP-mode is still WIP.
Maybe you can save you alot trouble if your mobile can connect to ad-hoc wifis.

have you installed crda and udev on your box?

TX failures? do you have hostapd's log of it?

well, you have a 32-bit architecture, unlike me or larry.
So, with a bit of luck the skbs always fitted into a single page and you never
had problems with memory fragmentation.

Do keyboard-leds "flash" when it locks up, or does console respond 
if you press alt-sysrq-m / alt-sysrq-w on the connected keyboard?
( If your box has a serial port, you can try to get the logs from there...  )
