Message-ID:  <E1Nr8P1-0002sn-00.msnkipa-mail-ru@f16.mail.ru>

There is FreeBSD8 system (cvsup`ed and recompiled kernel on PC-BSD system). Noteboot asus a3l with intel PRO wireless 2915 card. Wireless 802.11a network with WPA2 protection. I configure my system as following (rc.conf):
dhclient_flags="-c /etc/dhclient.conf"
synchronous_dhclient="YES"
ifconfig_rl0="DHCP"
ifconfig_iwi0="up"
wlans_iwi0="wlan0"
ifconfig_wlan0="WPA DHCP bmiss 200 roaming auto"
hostname="asus-a3l"

Problem: After long idle (about 50 minutes) iwi driver timed out without reason. If I have permanently working ping utility driver work well. But as I turn it off it timed out:

Mar 15 07:44:29 asus-a3l kernel: iwi0: device timeout

I tried to sysctl debug.iwi=2 but there is no information before first "iwi0: device timeout" message only after. What can I do to force my system works correctly?
