Root mount waiting for...

Today I have svn up from r190569 to r190813, did make buildworld and 
recompiled kernel. System boots normaly, but  when root file system should 
be mounted I see this message:

Root mount waiting for: and some silly symbols after that. This keeps 
repating.. Here is my  dmesg  from working kernel from r190469:
