Fiasco.OC on amd64 Opteron 6000

Hi,
I'm trying to run Fiasco.OC amd64 build on an Opteron 6100 magny-cours 
series (4-way-SMP, 12-cores-per-chip).  When it boots it is as if the 
scheduling interrupt on the local APIC is not getting set up correctly.  
It also warns about some errata.  It does boot with MP disabled, and RTC 
for the scheduling - not much use on a 48-core machine though ;-)

Any clues??? Thanks,
Daniel
