Title:
  [Lenovo IdeaPad S10-3] Wireless and Bluetooth switch does not work
  correctly on lenovo ideapad s10-3

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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.

  WORKAROUND: After a suspend and wake, do:
  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.
  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.
