[Bug 577114] [NEW] Wireless and Bluetooth switch does not work correctly on lenovo ideapad s10-3

[Michael Mess]

Public bug reported:

Binary package hint: linux-image-2.6.32-21-generic

I have installed Ubuntu from CD [Ubuntu-Netbook 10.04 _Lucid Lynx_ -
Beta i386 (20100318)] Wireless has been detected automatically and
everything worked fine.

One day after installing updates on the 26.04.2010, i noticed that after Booting the Wireless interface and bluetooth is disabled, regardless of the wireless switch.
It seems that the switch is turned off, regardless if the switch is on or off, even Fn-F5 (Software-Switch for Wireless/Bluetooth) does not help.
I have found the following workaround:

Switch the laptop into Suspend mode and wake it up again. Then do a

# sudo rmmod ath9k
# sudo modprobe ath9k

Then wireless is available and connects automatically. Bluetooth is also
available. Everything works fine then.

But when booting the kernel from power off, the wireless led is on when grub is shown and gets turned off, when the kernel boots and both, Wlan and Bluetooth are disabled.
To get it working I have to use the workaround with suspend/wakup and reloading the ath9k module to get Wlan working.
When Wlan is working and I turn off the wireless hardware switch, Wlan and Bluetooth gets disabled as expected, but when I turn it on again, it does not get reactivated and I have to do the workaround again to get it working again.

I don't think that it is defective hardware, because:
  * Before the problem appeared the first time, everything was working fine.
  * After doing the workaround, everything works fine
  * The wlan led is on in the grub menu, but it turns off, when the kernel is loaded.
