Hello, The reason of my writing is that an error message of our webserver asked me to do so. We're running a dual Opteron system and when booting up, the following error is shown. It's in no way critical to the operation of the system. Everything works normal. Output of dmesg: IO APIC #3...... .... register #00: 03000000 ....... : physical APIC id: 03 ....... : Delivery Type: 0 ....... : LTS : 0 .... register #01: 00030011 ....... : max redirection entries: 0003 An unexpected IO-APIC was found.
