kern/165212: [ath] No WiFi on Acer Aspire One 751h (Atheros AR5BHB63 & AR5B95)

[Adrian Chadd]

I bet it's that. Rfkill and acpi can be a pain. Ath5k and ath9k have had issues with it in the past.

I'll see if my acer sspire one (running windows) has the same issue when booting freebsd..

 OK.  I tried to attach the previous message, too, but I assume the

 system was unhappy with the 180KB+ log file.

 There is such a switch.  I have tried playing with it under FreeBSD,

 and got nowhere.  I don't seem to have to touch it under Ubuntu (or

 maybe I only had to use it once).

 Other than having FreeBSD try to use ACPI, I don't know anything about this.

 This appears in the boot log, and might be relevant:

 

 Feb 20 16:11:25 halfpint kernel: acpi0: <ACRSYS ACRPRDCT> on motherboard

 Feb 20 16:11:25 halfpint kernel: ACPI Error: Could not enable PowerButton event (20120215/evxfevnt-217)

 Feb 20 16:11:25 halfpint kernel: ACPI Warning: Could not enable fixed event 0x2 (20120215/evxface-575)

 Feb 20 16:11:25 halfpint kernel: acpi0: Power Button (fixed)

 Feb 20 16:11:25 halfpint kernel: acpi0: reservation of 3f800000, 70800000 (3) failed

 Feb 20 16:11:25 halfpint kernel: cpu0: <ACPI CPU> on acpi0

 Feb 20 16:11:25 halfpint kernel: cpu1: <ACPI CPU> on acpi0

 

 How do I find out if there is an ACPI module available, and if so, how to load

 and enable it?  When I got this netbook it had a dead hard disk (i.e. no software),

 and no useful documentation.  I have downloaded the available user and quick start

 guides from Acer but I don't see much useful info.
