Interesting. I'm having the same problem, intermittently, with kernel
3.18.3. I haven't had a chance to do much regression testing though,
and have since moved to 3.19 kernels which don't seem to have this
problem. The handful of 3.18.3 boots I've tried, it always booted with
nomodeset; and only intermittently failed without it. So I figured it
was some video regression...

What happens if you remove 'rhgb quiet' and add 'nomodeset' parameter?
