I think it's a different problem. I reproduced the same with 2.4.0-test12 but not 2.4.0-test10.
There are changes (not very large) in fs/devfs/base.c between these versions. I tried to take 2.4.0 and change back these updates and saw that it doesn't fix the problem. Trying all prerelaeses between 2.4.0-test10 and 2.4.0-test12 perhaps would take too much time ...
There is no hanging (or crashes) at all for me. All these versions boots Ok for me, but what I have is devfsd quitting with error message that it cannot state /dev/vcc/[1-6] after some relooging from the same terminal.
