[Bug 1416847] Re: kerneloops on suspend from resume


While the Yoga 2 13 is in no way shipped by Lenovo, their acpi tables do
have an exception for _OSI(Linux). Which makes me wonder if that's just
to blacklist things.

Someone more knowledgable on this list may want to shed some light.

        Method (_INI, 0, NotSerialized)  // _INI: Initialize
            Store (0x07D0, OSYS) /* \OSYS */
            If (CondRefOf (\_OSI, Local0))
                If (_OSI ("Windows 2001"))
                    Store (0x07D1, OSYS) /* \OSYS */

                If (_OSI ("Windows 2001 SP1"))
                    Store (0x07D1, OSYS) /* \OSYS */

                If (_OSI ("Windows 2001 SP2"))
                    Store (0x07D2, OSYS) /* \OSYS */

                If (_OSI ("Windows 2001.1"))
                    Store (0x07D3, OSYS) /* \OSYS */

                If (_OSI ("Windows 2006"))
                    Store (0x07D6, OSYS) /* \OSYS */

                If (_OSI ("Windows 2009"))
                    Store (0x07D9, OSYS) /* \OSYS */

                If (_OSI ("Windows 2012"))
                    Store (0x07DC, OSYS) /* \OSYS */

                If (_OSI ("Windows 2013"))
                    Store (0x07DD, OSYS) /* \OSYS */

                If (_OSI ("Linux"))
                    Store (0x03E8, OSYS) /* \OSYS */
