There is/was a bug/issue going around with a recent kernel change where there wasn't enough entropy available and the system was waiting. Moving your mouse would generate the needed entropy and the system boot would continue. Here is a post about it.

To confirm if this is the issue, there should be some log entries in your journal related to "random" and "uninitialized urandom read".

In Arch a similar problem was fixed by installed and enabling haveged.
