On boot of my Compaq Presario C571NR running LFS with kernel 2.6.22.1 I receive the following messages: Sep 22 08:38:07 localhost kernel: ACPI: BIOS bug: multiple APIC/MADT found, using 0 Sep 22 08:38:07 localhost kernel: ACPI: If "acpi_apic_instance=2" works better, notify linux-acpi@xxxxxxxxxxxxxxx << and >> Sep 22 08:38:07 localhost kernel: ACPI: System BIOS is requesting _OSI(Linux) Sep 22 08:38:07 localhost kernel: ACPI: Please test with "acpi_osi=!Linux" Sep 22 08:38:07 localhost kernel: Please send dmidecode to linux-acpi@xxxxxxxxxxxxxxx I see no obvious usability differences with acpi_apic_instance=2, is there something specific I can check for? I do have intermittent suspend problems, but I'm not sure this flag has any effect on suspend code. Also, attached is the dmidecode output as requested. ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC - 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
