I already googled this, there are patches on 2.4.x kernel but i dont like downgrading the kernel. Or if someone already did a kernel tweaking/hacking about these issues it would help. NOTE: I don't think that there are bugs/problems on the BIOS because this box has been already tested and runs smoothly without any problems and issues on FreeBSD 6.1 ## DMESG SHOWS THE MP-BIOS BUG ## [root@localhost ~]# dmesg |grep -i APIC ACPI: Local APIC address 0xfee00000 ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled) Processor #0 15:15 APIC version 16 ACPI: LAPIC (acpi_id[0x01] lapic_id[0x01] disabled) ACPI: LAPIC_NMI (acpi_id[0x00] high edge lint[0x1]) ACPI: LAPIC_NMI (acpi_id[0x01] high edge lint[0x1]) ACPI: IOAPIC (id[0x02] address[0xfec00000] gsi_base[0]) IOAPIC[0]: apic_id 2, version 33, address 0xfec00000, GSI 0-23 Setting APIC routing to flat ..MP-BIOS bug: 8254 timer not connected to IO-APIC <---*HERE'S THE SAID BUG* Using local APIC timer interrupts.
