Do you notice any functional difference when booting with... "acpi_osi=Linux" (default for 2.6.22 and earlier) vs. "acpi_osi=!Linux" (default for 2.6.23 and later) ...in particular, please check sound, wifi, and hibernate. Also, please send me the output from acpidump. thanks, -Len ps If you don't have acpidump, you can get it from pmtools here: http://www.lesswatts.org/projects/acpi/utilities.php - 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
