Bug Description
This Notebook runs SLES 11 (SP1) with working wifi and bluetooth with working light for key on Fn+F12. After installing Ubuntu 12.04 wifi stopped working.
I tried to track down the issue, as far as I can say there is an issue in either ath9k or/and hp-wim
Problem: Hardwarekey Fn+F12 doen't change the light on the keyboard between white (on) and orange (off). The light change while booting from orange (off) to white (on) and stays there, no matter what I do!
There are four devices in rfkill:
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
6: phy1: Wireless LAN
Soft blocked: no
Hard blocked: yes
9: hp-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no
10: hp-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
device 9 and 10 are belonging to hp-wmi. If I rmmod the hp-wmi driver those two devices are gone and Fn+F12 does nothing.
If driver is active Fn+F12 toggle 9 and 10 (light is not updated!) but not the phy (dev 6) or hci (dev 0). Since hci is not blocked by default bluetooth is working, but wifi is blocked on boot. There is no BIOS option in the HP635 to enable wifi!
Even worst if I call "rfkill unblock all" events occour for all four devices, but hp-wifi (dev 9) and hp-bluetooth (dev 10) stay on soft blocked: yes! Bluetooth unity gui element obviously scans for dev 10 and always report an deactivated bluetooth connection. (But Bluetooth is working since hci0 is unblocked and running!)
There is a commit for hp-wmi which plays around with soft & hard block stats
http://
which could cause some of the problems above.
summery:
hardware button don't toggle wifi and bluetooth hardware blocks only hp-wmi hardware blocks
software button toggle software blocks for some devs, but hp-wmi software blocks aren't touched. It is impossible to have all blocks to "unblock"

Would it be possible for you to test the latest upstream kernel? Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed by the mainline kernel, please add the following tag 'kernel- fixed-upstream- KERNEL- VERSION' . For example, if kernel version 3.3-rc6 fixed the issue, the tag would be: 'kernel- fixed-upstream- v3.3-rc6' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.
