freebsd stable - Feb 2009 - Problem with transfering system to new disk.

Running system FreeBSD 6.2, attaching new disk (WD 750GB SATA RE3) map 
it thru Sysinstall and rsync old system to it.
Now trying to boot from new disk: system boots well to "Choose what to 
boot" screen (eg 1. normal 2 acpi disable 3. safe 4. single etc), after 
that  system continuously keep printing some strange strings like 
"csh=4583" can`t really read it cause it`s too fast, system don`t
react
to C-C C-X or even CTRL ALT DEL.
So, the question what is it... and how to fix it.
