[CentOS] 4.2 Lockup on Fujitsu-Siemens Primergy Econel 200

Hello everybody,

I'm looking for some insights on reproductible lockups with this server
so please bear the long description that follows:

Installed the 4.0 Centos than yum updated it so it results a 4.2 Centos
fully updated. During the instalation and update there were no cold
boots. That's important because if (updated Centos or not) you cold boot
the server it stucks at the "configuring hardware ... storage" step. It
does not matter the kernel version but if i choose the SMP kernels it
freezes just a little later on "configuring hardware ... audio" step.It
freezes at the same spot without kernel panicking. 
I altered the rc.sysinit file so that at the configuring hardware step
it does not load any modules. It passes (forcefully) the configuring
hardware step but it freezes at the next "Configuring kernel parameters"
step. There are no errors in the log as the k(logd) is not started at
that point.

For a change, i installed a FC2 and it's stable. However i want that
Centos running!

Please give me some advice.

CM
