seems you have been there too ;)
I still do remember once we had to deal with very new and not well 
documented processor from big name in industry, after several prototypes we 
finally found the only person in the company who had detailed knowledge on 
the part and let us know some internal info about the onchip DCDC which 
refused to work no matter how we layout the PCBs, and messing up with the 
SDRAM by injecting noise on the RAM high speed signals,  so we  finally got 
it to work, but we spent 9 months and our internal cost just of direct labor 
and materials went over 15K EURO
