I also just became aware of a tool that could help us fix the problem reading wlan state on your machine rather than just avoiding it. Please download the acer_ec.pl script from:
Then please execute the following sequences. Note that the page says that there is a possibility that the script could lock up your machine, so it's best to run it with all applications closed, etc.
Sequence #1:
1. Start with a fresh boot (presumably wifi is enabled and working)
2. Run 'perl acer_ec.pl regs > wlan-pre-rfkill'
3. Run 'rfkill block <n>', whiere <n> is the index for the acer-wireless switch
4. Run 'perl acer_ec.pl regs > wlan-post-rfkill'
5. Repeat 2-4 above for the acer-threeg switch, changing the output filenames accordingly
Sequence #2:
1. Start with a fresh boot (presumably wifi is enabled and working)
2. Run 'sudo rmmod acer-wmi'
3. Run 'perl acer_ec.pl regs > wlan-pre-hotkey'
4. Press the wlan hotkey
5. Run 'perl acer_ec.pl regs > wlan-post-hotkey'
Please attach all of the output files.
Thanks for all the testing! We should be just about done.
