I have had same problem. And problem happened to me again today when I 
installed 3.1 on my laptop.

To work-around this problem, I stopped my boot loader by pressing space 
bar. Then ran "boot -c".

Then at the userconf prompt I typed "disable ohci" and then "quit".

Then I could boot.

Please see PRs 34100 and 34203:

It also suggests using different kernel.

Is this going to be fixed? As it appears more and more systems have this 
problem.
