I also experience similar hangs, with a F20 system with mesa 10.3.3. In total,
I have F20 installed on four systems, two using the nvidia kernel driver, one
with i915 and one with radeon. Only the radeon system experience hangs. I get

I can not pinpoint one specific action which triggers the hang. First time it
was firefox, next time Konsole and other times it simply hangs a while after
locking the screen. I am considering downgrading mesa. Let me know if there are
other measures I can take to help resolving this bug.
