It also means that OSI(Linux) was enabled, which means you were running 2.6.22. > Jan 22 09:46:26 IT-Manager kernel: [ 0.652000] ACPI: System BIOS is requesting _OSI(Linux) > Jan 22 09:46:26 IT-Manager kernel: [ 0.652000] ACPI: Please test with "acpi_osi=!Linux" this also means that you are running 2.6.22, which had OSI(Linux) enabled by default and wasn't smart enough to change the line above when there was a cmdline override. 2.6.23 is just as dumb, but with the opposite polarity:-) The patch for 2.6.24 will be a little more clever, and I'll probably send it to 2.6.23.stable as well... thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
