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) Please send me the output from acpidump. I've got this box in the blacklist already b/c similar machines showed that OSI(Linux) on them is a NOP. 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
