Hi Fabio,

Does rfkill button means Fn+F12 key on your machine?

Looks your machine emit e078 code when it switch to Windows 8 code path. Please tail your log and press Fn key for make sure it emit e078 code.
I didn't see e078 code in hewlett-packard keymap file in udev, currently it define 0xD7 to be the wlan key.

hmm... this machine changed wlan0 status on working kernel and also emit e078 code like on Windows 8 mode.
Then I think your machine control RF power by different way but BIOS, maybe wmi or other ways.
Please attached on your DSDT, hope OEM do those things through ACPI.

Please try acpi_osi="!Windows 2012", it will switch back to Windows 2009 mode. Then look at does things better than before?
Thanks a lot! Joey Lee
