It's all very simple; we ask the owners of these machines if acpi_osi="!Windows 2012" makes things work better, if they do, they go into the blacklist, if not, they don't. That would fix the problems for these machines *today*. If later it turns out there are other issues introduced, they get removed, just like you removed the intel_backlight switch patch. Igor Gnatenko said he had problems, but didn't mention which problem. In bug #51231, tons of people reported that things improved for ThinkPad X230. And when the proper fix is done, everyone will be happy and we can drop the blacklist. Everybody benefits this way. -- Felipe Contreras -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
