Subject: warning in arch/x86/kernel/cpu/mtrr/generic.c:400 with 2.6.29-rc3 on IBM x3400

Hi,

just for fun i installed linux 2.6.29-rc3 on a IBM x3400 server for
testing purposes and get a warning in
arch/x86/kernel/cpu/mtrr/generic.c:

Kernel failure message 1:

Bios is the newest IBM BIOS.
There are no problems with previous kernel versions like 2.6.18-92 or
2.6.27.

Any ideas about the CPU/BIOS warning?
