p54: hardware wifi button doesn't activate wifi on this notebook
Last modified: 2013-01-02 08:16:45 EST
Description of problem: After upgrading to F17, I can't enable wifi on this notebook. When I press the button, the led lits up, but "rfkill list" still says it's hardblocked. As does the NM-applet. But when I reboot the machine it starts working.
Version-Release number of selected component (if applicable): rfkill-0.4-5.fc17
How reproducible: always
Steps to Reproduce:
1. enable wifi
2. nothing happens
atkbd serio0: Use 'setkeycode e076 <keycode>' to make it known
Expected results: working wifi
Additional info: I'm not sure if rfkill is the right component, maybe the msi_laptop kernel module is to blame?
It sounds like the platform driver isn't properly updating the state after reading it at boot time?
Looks like. Jan, could you provide the output of
while the machine is in the broken state?
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
but the LED is on, and the wifi card should be working.
That's the full output? In that case the problem is with the wifi driver, not with msi-laptop.
yes, that's the full output
What is the driver in question? Can we see the output from dmesg after you boot with wireless disabled, then attempt to enable the wireless by pressing the button to light the LED?
It's a p54 chipset. At 94.xx I press the hardware button to turn on wifi:

Is this still an issue with 3.5.3 kernels currently in updates?
