Dell Poweredge 1950, boot problem

[Sergey Lyubka]

I figured out, that the APIC is responsible for that. If APIC is
turned off, then the box boots fine (although it cannot see more that
1 CPU). Here  is the dmesg with APIC disabled:

However, with APIC turned on, the boot stops here:

<---- hang --->


It looks like it stopped on ses0 detection. The hang is nasty: event
the powercycle button didn't work, I had to unplug the power led and
plug it again. Any ideas ? Please advise.
