I would inspect services which start after networking but before ssh.
A udev rule can easily hang a boot as the calls often block.
I would then try only starting essential services (reduce the runlevel if possible, only networking & ssh).

I would replace the LABEL statement with the partition id (/dev/hdd1 ?), parsing label's and uuid's can occasionally trip up.

Restarting a service as a root login is not the same as starting a service at boot.
Any one of these services may be hanging the boot but not hang from a root login (commonly root's environment, e.g. $PATH masks an issue).

This advice is worth exactly what you paid for it, good luck.
