Comment 14 for bug 771758

Mauricio, yours really does appear to be a different issue. Do you have a hotkey for wifi on your machine? Does it have any effect on the rfkill state?

I built a test kernel with some additional logging. Please install this kernel, reboot, and run 'rfkill unblock all' several times (space them out by at least 30 seconds, not one right after another). Then collect the output of dmesg and attach it here. The kernel is available at:

Please also run the command 'sudo fwts --disassemble-aml' (you will probably need to install the fwts package) and attach the *.dsl files it generates here as well.

Thanks!
