Hi Bernd,

This:

May 24 16:14:48 ucs kernel: .... register #01: 00030011
May 24 16:14:48 ucs kernel: ....... : max redirection entries: 0003
May 24 16:14:48 ucs kernel: An unexpected IO-APIC was found. If this kernel release is less than
May 24 16:14:48 ucs kernel: three months old please report this to linux-smp@vger.kernel.org
May 24 16:14:48 ucs kernel: ....... : PRQ implemented: 0
May 24 16:14:48 ucs kernel: ....... : IO APIC version: 0011

is complaining about the value 3 for "max redirection entries".
However, linux 2.4.30 from www.kernel.org already checks for and
allows a value of 3 for that field, so I don't know quite what
to think about this other than to question (wonder) what this
kernel version means:

May 24 16:14:48 ucs kernel: Linux version 2.4.30.digitec.20050524 (root@ucs) (gcc version 3.3.2 20030908 (Debian prerelease)) #1 SMP Tue May 24 15:43:06 CEST 2005
