Problem enabling wireless (ACPI errors)

I upgraded my Acer 9301 laptop from Fedora 16 to Fedora 17. Now I can't enable wireless networks in KDE. When I boot, the LED for WLAN is lit, which indicates that it is enabled. However, KDE NetworkManager says that the WLAN Interface is Unavailable.

ifconfig shows interface eth0, but it is not UP.

I have attached lines from dmesg relating to ath0 or ACPI in the attachment.

This is my chip:

[2012-04-27 18:09:06] ath5k phy0: Atheros AR2413 chip found (MAC: 0x78, PHY: 0x45)

When I try to enable wireless, I get:

[2012-04-27 18:14:28] ACPI: EC: GPE storm detected, transactions will use polling mode
[2012-04-27 18:15:16] ADDRCONF(NETDEV_UP): ath0: link is not ready

And when I push the WLAN button, I get:

[2012-04-26 23:54:25] ADDRCONF(NETDEV_UP): ath0: link is not ready
[2012-04-26 23:54:48] ACPI Error: [CB04] Namespace lookup failure, AE_ALREADY_EXISTS (20120111/dsfield-143)
[2012-04-26 23:54:48] ACPI Error: Method parse/execution failed [\_SB_.AMW0.WMCA] (Node f682fc30), AE_ALREADY_EXISTS (20120111/psparse-536)
[2012-04-26 23:54:48] ACPI: Marking method WMCA as Serialized because of AE_ALREADY_EXISTS error

I have these versions:


Any ideas?

Re: Problem enabling wireless (ACPI errors)

Not sure it's the same, but I have a similar issue with my atheros card under gnome, so I filed this bug report:

Re: Problem enabling wireless (ACPI errors)

WLAN works in kernel kernel-3.3.0-1.fc17.i686 but not in kernel-3.3.2-8.fc17.i686.

In kernel-3.3.0-1.fc17.i686 I have to clear the check box "Enable wireless" and then mark it again. After that WLAN works.

There are no ACPI errors in dmesg.

I updated to the latest packages now, and kernel 3.3.4-1.fc17.i686 has the same problem. However, it seems that dmesg contains no ACPI errors this time.
