Very similar behavior with Trusty. My best luck is to choose recovery from grub menu and simply "resume" from there. That gets me fairly consistent log in though it's crashed a few times as well.
I have spare drives and a different AMD box I can test with as well as a Macbook Pro.

AMD64bit install plagued with soft lock CPU on boot up. Sometimes I can boot into the desktop and everything seems fine. Other times I'll get into the desktop and everything locks up immediately. Most of the time, however, I cannot even fully boot. Bootup gets stuck with CPU Soft Lock on several cores. I tried boot loooping and can hardly get 2 successful boots in a row. Processor is AMD FX 8120. 16 GB of Ram. Installed on several hard drives with same problem. Nvidia Geforce 550ti Graphics. Issue arises with and without nvidia-current installed. Tried clean install. Tried upgrading from 13.04. Tried installing 13.10 server. All have same issue. 13.10 works fine on my intel macbook pro. What information can I add?
