problem processor HP 580 G5


I have 4 processors (quad core) on my server and I installed RedHat AS4 update 6 with the default configuration (SMP kernel 2.6.9-67).
The system detects only 2 processors (physical_id 0 and 2 in /proc/cpuinfo, same with the top command).

I tested a live CD with kernel version 2.6.23, it detected all processors.

The number of processor is not limited by RedHat AS, maybe there is a special configuration has put in place?

Thanks in advance.
