<pre>Now fixed in x86/tip.
If you want to report some details of the hang, otherwise there's not much I
can do.
The reason why it suddenly became worse is all due to switching to modesetting,
which only used rcs and so we end up interesting behaviour with X getting stuck
behind extra frames, and not reporting the buffer as idle as early (so the
client would be waiting on the CPU fence being signaled and not waiting on the
GPU, so being invisible to the waitboost mechanism). Interesting effect.</pre>
