Boot code broken in some way in recent current (Was: Panic at boot)

Hi,

    Sorry for bad problem description in my previous message.  Now I'll 
try to be
more accurate.

    At first I have two SMP system (Dual) one that boots normaly and one 
that
goes to panic (the older pc).
   I've setup finaly serial console to that system, so here is more 
detailed output:

OK boot -Dhv

It seems that this problem was introduced with recent bootloader update.
That is all a able to tell now.
