I'll see if I can get anywhere from there. Today I had some time on my hands and decided to get this working. Which I did. So the difference between 2.6.37 and 2.6.38 is that now I have to invoke rfkill to enable my wireless device, because pressing Fn + F2 toggles the hard and soft lock states of the device _but_ only to 'yes'. Pressing the key combination again will only remove the hard lock. On 2.6.37 it would remove both. For example: On 2.6.37: # rfkill list 0 # wifi disabled 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes # rfkill list 0 # wifi enabled (via Fn + F2) 0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no (rfkill events) 1301758599.537508: idx 0 type 1 op 2 soft 0 hard 0 1301758600.561087: idx 2 type 1 op 2 soft 0 hard 0 On 2.6.38: # rfkill list 0 # wifi disabled 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes # rfkill list 0 # wifi enabled (via Fn + F2) 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: no (rfkill events) 1301758830.251541: idx 0 type 1 op 2 soft 1 hard 0 Is there supposed to be a piece of software that listens for these events and toggles the soft state whenever the hard state changes?
