Comment 56 for bug 136529

I want to add to jtholmes summary above about the problem: for me logging in did not work even the first time on the first boot. I had to try several times before I got a successful login. What did solve the problem for me however, was putting the computer in uniprocessor mode, ie. disabling Hyperthreading in my case. What seems to be common for me and some other people here is that I have an Nvidia graphics card.
