Good tip. But I would check the keyboard cable, test the keys. At the same time, you will clean the laptop from dust.

Just to be clear:
Is this only happening when you enter single user mode?
'Normal', multi user mode works fine?
 
Just want to chime in that something like this sporadically happens for me too.

I never had it in single-user mode because I don't need to use it too much.
But in normal mode sometimes a VT just stops responding.
I can still switch to a different VT and it would work okay, but the original VT is kind of frozen.

The latest instance happened half-way through typing login password.
Stack trace from procstat is not remarkable:
Code: 
  PID    TID COMM                TDNAME              KSTACK
