proc isn't mounted then

mount /proc

(the entry in fstab should take care of the actual mounting)

sounds like it hung on shutdown, may be a sign of a more serious

ok, thats good then.

does the system mount any nfs file systems? one cause of hanging
on shutdown is often trying to unmount a nfs file system that is no
longer accessable. is network connectivity on the box ok? you should
be able to boot to single user mode or at least linux emergency, and
manually configure the network card with ifconfig, so at least you
can use ping to be sure the driver/NIC/cable/switch is working

a system may hang on bootup depending on it's network configuration
as well, though I haven't seen a system hang at the point where your
email indicates before.
