> Hi,

> on my Fujitsu Lifebook E753 I experienced some "regressions" with
> current kernel versions compared to linux 3.5 (used in Ubuntu 12.04
> for instance):
> - on bootup backlight is extremely dark (I can change it though)
> - the wireless button does not work any more
> Today I did a bisect and found out, that the "regression" was
> introduced with commit "a57f7f9175b8ccbc9df83ac13860488913115de4".
> Searching the internet I read about a bootloader option
> "acpi_osi="!Windows 2012" which solved the issue for me.
> If you want/need some further information for a patch just tell me. I
> don't have any insight into ACPI escpecially the new Windows8 changes
> so if you can't do anything about it I apologize for the noise.

HI:
Could you apply a bug on the https://bugzilla.kernel.org with the
output of acpidump?
