OK - now we have to play the thousand questions game ;-)

This happens after the system is up?
Can you send me the startup messages (With verbose enabled)?
Are there known issues with other operating systems?
Do you have a serial console / serial line for gdb / firewire 
for debugging ?

If I read your first posting correctly you have 6 pentium II overdrive
processors in your system (overdrive = PII with PPRO pinout).
Can you supply information about the vendor / chipset of your system?
