Hi.

I have hostapd 0.5.2 (hostap driver 0.4.7) with prism2.5 on 2.4.31 kernel
(WE 18). Firmware 1.7.4 and 1.1.1.
Have configuration with  WPA (TKIP), 802.1x EAP-TTLS, outside radius
server and enabled kernels crypto-api.

I'm trying some wireless ethernet adapters which use WPA.
I try Linksys WET54G and Zyxel G-405. But have problems with both of them.
After some time (tens of minutes, or some hours) client stop responding.
Sometimes help when i try reaunteticate on client (or just power off/on),
but sometimes my prism2.5 card stop responding and works after i use
iwpriv wlan0 reset 0 (or 1).

I try to debug some output but cannot find problems. It seems to me that
problems is client but i'm not sure.

Here are some error messages what i capture. Some of them are from dmesg.
Can you tell me pls what that errors mean (some explanation)  and why they
appears ?

1. When i try Linksys i have lot of these in dmesg:
