It seems to hang in smp_core99_kick_cpu(), probably when the CPU takes
the exception.  I inserted some debug messages around the call to
mdelay() like so:

 if (ppc_md.progress) ppc_md.progress("!", 0);
 mdelay(1);
 if (ppc_md.progress) ppc_md.progress("smp_core99_kick_cpu: after mdelay", 0);

When booting, "!" is printed, but the other message is not.

Is there anything else I can do to diagnose the problem?
