Hello All,
I am ruining Centos 6.2 final on IBM System x3200 M2 -[4368I1S].
BOIS : IBM BIOS Version 1.43 -[GUE143AUS-1.43]
CPU : Intel(R) Xeon(R) CPU E3110 @ 3.00GHz
I am getting below mentioned error in messages when system boot.

Server is working fine but it rebooting automatically. We have checked the
server
power supply, RAM and both are good. There is no any power fluctuation.
It seems the above error is causing the reboot issue.
I have updated kernel to latest one kernel /vmlinuz-2.6.32-431.5.1.el6.x86_64,
previous it was kernel /vmlinuz-2.6.32-220.13.1.el6.
On new kernel same error is coming.
I have also boot the server with pci=nocrs and got same error.

I have searched on google and found bug 23442 listed on kernel bugzila. I have
also checked the https://bugs.acpica.org/show_bug.cgi?id=946 and on
bugs.acpica.org it is mentioned that there is no any issue with ACPI.
Please suggest where is the problem, in BIOS, ACPI, in kernel or hardware.
Many many thanks in advance.
