---------------------------------------+------------------------------------
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
Dmesg tells me (over and over):

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.
