Since the CPU is stalled and unable to make further progress something 
is inhibiting it.
One thought - I wonder if the CPU is waiting for memory IO - in which 
case do you have sufficient memory for the load on the cpu and do you 
have swap set up? Also it may be worthwhile running memcheck to be sure 
your memory is not faulty.
