info: unexpected IO-APIC found

[MARTIN KONIETZKE]

hi,

this comes up on linux with kernel 2.4.21 (patched with sgi-xfs)
on a dell workstation 360 with 3GHz Pentium IV :



Setting 1 in the phys_id_present_map
...changing IO-APIC physical APIC ID to 1 ... ok.
init IO_APIC IRQs
 IO-APIC (apicid-pin) 1-0, 1-13 not connected.
..TIMER: vector=0x31 pin1=2 pin2=0
number of MP IRQ sources: 40.
number of IO-APIC #1 registers: 24.
testing the IO APIC.......................

IO APIC #1......
.... register #00: 01000000
.......    : physical APIC id: 01
.......    : Delivery Type: 0
.......    : LTS          : 0
.... register #01: 00178020
.......     : max redirection entries: 0017
.......     : PRQ implemented: 1
.......     : IO APIC version: 0020
.... register #02: 00178020
.......     : arbitration: 00
An unexpected IO-APIC was found. If this kernel release is less than
three months old please report this to linux-smp@vger.kernel.org
