>Description:
When using a wireless client running FreeBSD 6.0-RC1 and wireless card D-Link DWL-520 with ahteros chipset, this system freezes after reboot command. Only after turn off by power button we can use again this machine.
This is critical because FreeBSD 6.0 has focus target to wireless devices.
There isn't problem if ath0 interface wasn't configure.
>How-To-Repeat:
Using a wireless card D-Link DWL-520, modify /boot/loader.conf:
wlan_wep_load="YES"
if_ath_load="YES"
ath_hal_load="YES"
ath_rate_load="YES"
and configure ath0 interface to associate with some AP, example /etc/start_if.ath0:
ifconfig ath0 inet A.B.C.D netmask 255.255.255.192 ssid 'SOMENETWORK' \
wepmode on wepkey 0x2020202020 weptxkey 1 media DS/2Mbps mode 11b
All is working but after run "reboot" command this system freezes after sync disks and print uptime.
We have tested with 03 different motherboards, one running Celeron and others AMD processors.
There isn't problem using same hardware and not configure ath0 interface. This problem appear only after stablish some wireless connection using ath0 internface
