Those "ath9k 0000:07:00.0: restoring config space at offset" messages look pretty wierd. I'm not sure what is happening there -- perhaps something on your device has been corrupted? I'll copy someone from the ath9k team, hoping that he has some insight. Could you also post the output of running "rfkill" on the command line? [root@canis /]# rfkill Usage: rfkill [options] command Options: --version show version (0.4) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: <idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm [root@canis /]# rfkill list 0: ideapad_wlan: Wireless LAN Soft blocked: yes Hard blocked: no 1: ideapad_bluetooth: Bluetooth Soft blocked: yes Hard blocked: no 2: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes [root@canis /]# I got the same error if I swicht off wifi and try to switch it on again. with rfkill unblock wifi I'm able to start it again. Activating it via gnome switch doesn't work as mentioned [mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update. [mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update. [mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update. Using kernel-3.3.0-4.fc16 the problem still remains, however I get the feeling that the issue lies somewhere else:
$andre:\> rfkill list
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
So there are two devices listed for Wireless LAN, and phy0 remains always hardblocked, also when running "rfkill unblock all", and that probably triggers the issue in the UI.
And I have no idea where these two entries come from and how to debug this.
$andre:\> lsmod | grep phy $andre:\> lsmod | grep ideapad ideapad_laptop 13670 0 sparse_keymap 13342 1 ideapad_laptop rfkill 20448 5 bluetooth,cfg80211,ideapad_laptop "rmmod -f ideapad_laptop" still does not fix the problem (and of course killed bluetooth in gnome-shell's panel - now only phy0 is still listed by rfkill). <tl;dr> SOLVED by workaround. Long version: After spending one and a half hour of reading a few dozens of webpages, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/577114/comments/69 worked for me (resetting BIOS to default). Note to myself: When this happens again also try https://bugs.launchpad.net/ubuntu/+source/linux/+bug/577114/comments/0 and NEVER EVER touch the hardware switch again.

I'm glad you got it working. Some systems depend by default on custom utilities in Windows to do certain things. Unless/until those system vendors provide similar utilities for Linux, we are largely at their mercy. At least in this case they provided for "normal" operation through the BIOS setting you found. |
