Interesintg could it be that master.passwd file corrupted (after power 
shutdown) and fsck corrected in background.. which resulted in such 
behaviour.

The strange thing with possibly empty password is that login from 
ip-console accepted correct password. So dont sure about empty...It 
seems like su was accepting any password at that time.

changes in critical system tools. Argh....and then anyway redeploy system.
