Here are my initial thoughts.

Sounds like a hardware problem to me. What about running a drive io test?
What does syslog say as far as kernel messages? 

And, what about booting with a rescue/standalone disk? Does that go just as
slow?

Seeing how disks are so cheap, you could buy another Hard Drive, drop it in,
see how it performs, and then just use it in an external enclosure.

But, there could be other problems I suppose? Is there something that would 
cause an "interrupt" that would cause the system to hang? I had a system that
had software flow control on the serial consoles and it would hang that
program. Could your tty be blocking?
