Hallo !

My penguin says: send this mail to you :-)

IO APIC #2......
.... register #00: 02000000
....... : physical APIC id: 02
.... register #01: 00178002
....... : max redirection entries: 0017
....... : PRQ implemented: 1
....... : IO APIC version: 0002
WARNING: unexpected IO-APIC, please mail
to linux-smp@vger.kernel.org

I attached the output of dmesg after booting to single user mode.
The message occurs on a MSI KT7-Ultra ARU Mainboard (VIA KT333 Chipset)

Liebe Gruesse, Schroettner Robert
