We have done some tests on three of Intel + nVidia configuration systems with OEM _OSI strings removed - while some bugs are still observed, ex. one out of three has suspend/resume issues, no system crashes were observed - the biggest issue that worries us. The positive results give us confident to ack the removal of the OEM _OSI strings. While our tests were not able to cover all p...

I''d like to send this patch to upstream lkml/linux-acpi, but I want to make sure that the x86 side wants this too. The _OSI method is a way for platform ACPI firmware to determine the features and capabilities of the OS running on the system. This is usually done by calling the _OSI method with various strings in the _INI method of an ACPI device. The strings are things like "Linux" or "Windows"....

I'm all for dropping then when that's the case, so please feel free to add ACKs from me to the patches in question at that point. Cheers, Rafael
