Simply hacking in an early call to init_call_single_data() helped
a bit.  I saw a few more kernel messages as all the cpus were
brought up and synchronized ITC with the boot cpu. Then the
system hung hard.  Last messages were:

Total of 16 processors activated (50724.86 BogoMIPS).
net_namespace: 296 bytes
DMI 2.3 present
