Hi, I got this when I booted: ACPI Exception (processor_throttling-0084): AE_NOT_FOUND, Evaluating _PTC [20070126] ACPI Exception (processor_throttling-0147): AE_NOT_FOUND, Evaluating _TSS [20070126] Is this a problem? As far as I can tell, all of the system's devices are working. Here's the dmesg output filtered by "ACPI": [ 0.000000] BIOS-e820: 000000003dee0000 - 000000003deec000 (ACPI data) [ 0.000000] BIOS-e820: 000000003deec000 - 000000003df00000 (ACPI NVS) [ 0.000000] ACPI: RSDP 000F7E00, 0014 (r0 HP ) [ 0.000000] ACPI: RSDT 3DEE76BB, 0040 (r1 HP 09B8 6040000 LTP 0) [ 0.000000] ACPI: FACP 3DEEBE8C, 0074 (r1 HP 09B8 6040000 PTL 50) [ 0.000000] ACPI: DSDT 3DEE7B9A, 42F2 (r1 HP 09B8 6040000 MSFT 100000E) [ 0.000000] ACPI: FACS 3DEFCFC0, 0040 [ 0.000000] ACPI: HPET 3DEEBF00, 0038 (r1 HP 09B8 6040000 PTL 0) [ 0.000000] ACPI: APIC 3DEEBF38, 005A (r1 HP 09B8 6040000 PTL 50) [ 0.000000] ACPI: APIC 3DEEBF92, 0046 (r1 HP 09B8 6040000 PTL 0) [ 0.000000] ACPI: BOOT 3DEEBFD8, 0028 (r1 HP 09B8 6040000 LTP 1) [ 0.000000] ACPI: SSDT 3DEE7AFE, 009C (r1 HP 09B8 1 INTL 20030224) [ 0.000000] ACPI: SSDT 3DEE76FB, 0277 (r1 HP 09B8 2000 INTL 20030224) [ 0.000000] ACPI: BIOS bug: multiple APIC/MADT found, using 0 [ 0.000000] ACPI: If "acpi_apic_instance=2" works better, notify linux-acpi@xxxxxxxxxxxxxxx [ 0.000000] ACPI: PM-Timer IO Port: 0x1008 [ 0.000000] ACPI: Local APIC address 0xfee00000 [ 0.000000] ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled) [ 0.000000] ACPI: LAPIC_NMI (acpi_id[0x00] high edge lint[0x1]) [ 0.000000] ACPI: IOAPIC (id[0x01] address[0xfec00000] gsi_base[0]) [ 0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl) [ 0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 high level) [ 0.000000] ACPI: IRQ0 used by override.
