AP interface(s?) stops working after a short while (5-10 minutes). Clients gets kicked
and can't reconnect. This has been verified on more than one platform (all we tried with this version).
Platform:
- Gateworks Cambria (ixp4xx)
- 3x Compex WLM54AG radio cards (two in adhoc mode and one in AP mode).
Software:
- Linux 2.6.27.6
- Hostapd 0.6.9

Also, not sure if it's related, but this sporadically shows up in dmesg:
wifi2: ath_fatal_tasklet: Hardware error; resetting.
Wifi2 being the AP interface.
