Hi- Several of these messages have been "fixed" in later versions of 2.4 and eliminated in Linux 2.6. They are informational only and don't affect the operations of Linux. They come from Linux having a known-valid list of IO APIC devices and that list not being updated very often (hence the message removal in Linux 2.6). > [root@localhost root]# dmesg > n CPU#1 > ESR value before enabling vector: 00000000 > ESR value after enabling vector: 00000000 > Calibrating delay loop... 3578.26 BogoMIPS > CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line) > CPU: L2 Cache: 1024K (64 bytes/line) > Intel machine check reporting enabled on CPU#1. > CPU: After generic, caps: 078bfbff e1d3fbff 00000000 00000000 > CPU: Common caps: 078bfbff e1d3fbff 00000000 00000000 > CPU1: AMD Opteron(tm) Processor 844 stepping 0a > Total of 2 processors activated (7156.53 BogoMIPS). > ENABLING IO-APIC IRQs > Setting 2 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 2 ... ok. > Setting 3 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 3 ... ok. > Setting 4 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 4 ... ok. > Setting 5 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 5 ... ok. > Setting 6 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 6 ... ok. > Setting 7 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 7 ... ok. > Setting 8 in the phys_id_present_map > ...changing IO-APIC physical APIC ID to 8 ... ok. > init IO_APIC IRQs > IO-APIC (apicid-pin) 2-0, 2-16, 2-18, 2-20, 2-21, 2-22, 2-23, 3-0, 4-0, 4-1, 4-2, 4-3, 5-1, 5-2, 5-3, 6-1, 6-2, 6-3, 7-1, 7-2, 7-3, 8-1, 8-2, 8-3 not connected. > ..TIMER: vector=0x31 pin1=2 pin2=0 > number of MP IRQ sources: 26. > number of IO-APIC #2 registers: 24. > number of IO-APIC #3 registers: 4. > number of IO-APIC #4 registers: 4. > number of IO-APIC #5 registers: 4. > number of IO-APIC #6 registers: 4. > number of IO-APIC #7 registers: 4. > number of IO-APIC #8 registers: 4. > testing the IO APIC....................... > > IO APIC #2...... > .... register #00: 02000000 > ....... : physical APIC id: 02 > ....... : Delivery Type: 0 > ....... : LTS : 0 > .... register #01: 00170011 > ....... : max redirection entries: 0017 > ....... : PRQ implemented: 0 > ....... : IO APIC version: 0011 > .... register #02: 02000000 > ....... : arbitration: 02 > ....
