Summary: Backlight dark and wireless button not working on Fujitsu E753 Product: ACPI Version: 2.5 Kernel Version: 3.9.7 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ACPICA-Core AssignedTo: acpi_acpica-c...@kernel-bugs.osdl.org ReportedBy: janhinnerk.sto...@gmail.com Regression: Yes On my Fujitsu Lifebook E753 I experienced some "regressions" with current kernel versions (e.g. 3.9.7) 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 Recently 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. I reported it on the linux-acpi mailing list and was asked to report it here and add a acpidump. Perhaps I have done something wrong but all I get is: Linux version not implemented yet Could not get ACPI tables, AE_SUPPORT If you need some additional information tell me.
