Description Majdi S. Abbas 2011-06-23 11:30:14 UTC
The Atheros driver correctly picks up the presence of the card, and we can attach it to wlan0:

ath0: <Atheros 5424/2424> mem 0xd0000000-0xd000ffff at device 0.0 on pci3
ath0: AR2425 mac 14.2 RF5424 phy 7.0
wlan0: Ethernet address: 00:25:56:0c:4e:88

However, since the card is not actually powered on (soft power switch that does not work under FreeBSD), we can't use it -- scan results (either via ifconfig or wpa_supplicant) in:

ath0: device timeout
ath0: device timeout
ath0: device timeout
ath0: device timeout
ath0: device timeout
ath0: device timeout

Additional information:

Kernel config file: (reproducible under GENERIC as well)

Fix: 

Works under Linux 2.6, using the acer-acpi module:

http://repo.or.cz/w/acer_acpi.git/tree

Card is automatically powered on boot under Linux 2.6.x kernels, and functions correctly, using that module.

FreeBSD has an ACPI-WMI module now, as well as ACPI modules for other vendors, and appears to just needs an implementation of the Acer bits.  

I am available for testing.
How-To-Repeat: Take any soft WiFi power Acer netbook or notebook, add FreeBSD (-HEAD is probably required since the ath driver in 7.x and 8.x did not work without patching.)
